For a Smooth Installation — Prepare You're probably eager to add a security system to your vehicle.
That's great. And you'll save a lot of money by installing it yourself. That's smart. But, please do not turn the first screw before you map out a complete, step-by-step plan of attack.
'Ready, Fire, Aim' is no way to install a security system. You don't have to do it all in one day. Break the job into bite-size pieces.
Verify that each segment of the system works as intended before moving on. For example:. Step 1 — Find a spot to mount the 'brain' (control module) and siren. Hook the siren, LED indicator and valet switch to the brain, taking great care to route and connect the wires in a safe, secure way. Connect the power and ground leads to the brain. Step 2 — Position your sensors in their intended mounting locations and connect them to the brain.
Test the coverage area of the sensors and make final adjustments before you fasten them down. Step 3 — Tie into your door triggers and your power door lock circuit for keyless entry. Tie into your dome light and parking light circuits. Test these functions. When everything is working properly, secure the brain to the mounting surface. If you have time to do it all in one day, fine.
But don't rush it. And don't drive your vehicle until you've secured any loose wiring. Remember to disconnect your negative battery cable before you start mounting and connecting your system components. That will keep you from running your battery down or short-circuiting any of your components. You'll need to have the battery cable connected while you test wire functions or switches.
But don't forget to unhook it before you splice wires. Check your vehicle owner's manual to see if there are any special procedures to follow when disconnecting the battery cables. Make Sure You Have the Tools You Need Before You Begin You probably already own the basics: screwdrivers, wrenches and an electric drill. In addition to these basic tools, you should have the following available:. A wire cutter/stripper.
For many vehicles, plug-in interconnect harnesses simplify security system connections. But even if you use a harness, you still may need to splice some wires together. To make secure wire connections, you need a soldering iron and/or a crimping tool. Use heat-shrink tubing or electrical tape to protect your connections. Use a multimeter to verify the functions of vehicle wires you splice into, or to determine what kinds of switches your vehicle has. You need to test the wire because car makers occasionally use different color wires than the ones specified on the wire color sheets.
We can provide these sheets for most vehicles. DO NOT USE A TEST LIGHT instead of a multimeter. Test lights draw too much current and could damage sensitive circuits in your vehicle. Mounting the Siren Mount the siren under the hood, high in the engine compartment, preferably at least 18 inches from heat sources such as exhaust manifolds, radiators and heater cores. Aim it parallel to the ground, or toward the ground. Never mount it with the horn facing up. Water can collect in the horn, causing the siren to malfunction.
In some vehicles, you can mount your siren to the inner fender panel. If you have a choice, pick the spot that's hardest for a thief to reach. Route the siren wires away from a thief's reach as well.
If you mount your siren to a metal surface, use sheet metal screws. Do not use drywall screws. If you mount your siren to a plastic inner fender, use nuts and bolts to secure it. Determine what's behind the mounting surface, so that your screws won't accidentally penetrate fuel lines, brake lines, vacuum lines, control cables or wire bundles. Mounting the Brain If you plan to use an interconnect harness, you must mount the brain near the plug-in point. If you're not using a harness, you have more flexibility.
Under the dash near the steering column is a likely spot. Pros:. It's close to many of the wires you may want to tie into. It's up high, so you should get good range with your remote control. It's easy to reach, which makes installation and service easier. Cons:.
An experienced thief will probably look there first and could silence the system by yanking wires out of the brain. If you're worried about that, look for a less obvious spot behind the dash (behind the glove box or behind a kick panel). Under a front seat is another suitable location.
Pros:. Once you remove the seat, it's a very convenient area in which to work.
Most seats are held in place by a bolt in each corner. It's reasonably accessible, but not too obvious to a thief. It is isolated from electrical interference. Cons:. If your car develops a leak or you leave a window down during a storm, the brain could end up in a puddle (you could elevate it on a block of wood to be safe). Your remote control range might suffer a bit and you'll probably have to extend most of the wiring. Warning: removing your seat could.
If you do need extra wire to extend the leads from the brain to switches, sensors or a power source, take the brain plug with you to the hardware store. Buy stranded wire that matches or exceeds the gauge (thickness) of the leads you need to extend. For sensors, 18 gauge or larger should work fine. For power leads, 16 gauge or larger is usually required.
If you put the brain under a seat, do not cover it with carpeting because too much heat could build up inside the brain. If you have a stereo amplifier under a seat, do not put the brain nearby. Electromagnetic radiation from the amp could interfere with the operation of the brain. Wherever you decide to put the brain, remember to check what's behind the mounting surface, so your screw won't accidentally penetrate fuel lines. Your alarm brain has a built-in pigtail-type antenna wire.
It is important that the wire point straight away from the brain (a drinking straw acts as a good reinforcement), or at a right angle to the brain. Do not cut or ground this wire. Sensors Position your sensors inside your vehicle, not in the engine compartment or anywhere else they could get wet.
Attach shock sensors solidly to a metal surface, using screws. Try to take advantage of an existing screw in your vehicle. If you can't find a good one, you'll have to supply your own screw.
As an alternative, you can strap the shock sensor down, using nylon wire ties. Do not use Velcro or tape. You should mount your shock sensor relatively close to the center of your vehicle (under the dash is good), so it can detect shocks away from front and back equally well.
When you adjust your shock sensor's sensitivity, apply impact from all sides of the vehicle. Keep in mind that an extremely sensitive setting yields the most false alarms. That's true of any sensor. Locate your motion sensor down low near the center of your vehicle.
Do not mount your motion sensor until you have thoroughly tested its coverage area. You may have to try a few different spots before you find the one that gives you the best results. Pin Switches The pin (plunger-type) switches that come with most alarms are optional. Their purpose is to trigger the siren when a door, hood or trunk opens.
In most cases, you can tie into the pin switches that are already in your car. Look for the switches that turn on the dome light when you open doors. Tap into the wires leading away from the switches. They can usually be found behind your kick panels. Some vehicles also have pin switches for the trunk and hood. Generally, the easiest place to tie into pin switches is at a floor-level courtesy light or a pin-switch wire behind a kick panel.
Pin switches can have either a negative (-) trigger or a positive (+) trigger. The vehicle wire color sheet that we can supply with your alarm tells you which kind your vehicle uses. If we do not offer a wire color sheet for your vehicle, here's an easy way to test your switches: With your multimeter set to the volt scale, connect the black probe to ground and the red probe to the wire you think is the pin switch wire.
A negative trigger switch will read 0 volts when the door is open and 12 volts when the door is closed. A positive switch will read 12 volts when the door is open and 0 volts when the door is closed.
How To Install A Nexon Car Alarm System
If your vehicle doesn't have pin switches, you can add the ones that may have come with your security system (we also sell them separately). Some vehicle manufacturers use mercury switches instead of pin switches for hood/trunk lights. They are extremely difficult to tie into, so you will probably want to install the pin switches that came with your alarm. When installing the pin switches, keep in mind that they require about 1/4' clearance above the mounting surface with the door, hood or trunk closed.
Never mount them in a drain path or in a pit or depression, where water might pool up. Mounting the Flashing LED Your security system comes with a little red flashing light, called an LED (Light Emitting Diode), that mounts in your dash or center console. Its purpose is to warn would-be thieves that a car security system is armed and ready to wail if they try to break in. Mount the LED in an area that is highly visible from both sides of the vehicle.
Check the hole-size requirement before drilling. Inspect the area behind the mounting surface to make sure there is sufficient clearance and a path for the wire. Connecting the Brain to Your Parking Light Wiring Your car will have its parking lights wired either off a single circuit or in a parallel configuration. Most European cars use a parallel circuit. Most American cars use a single circuit. If your car uses a parallel circuit, you will have to tie both sides into the parking light output wire of the brain, using a. The vehicle wire color sheet available from Crutchfield tells you where to find your vehicle's parking light wire.
If we do not offer a wire color sheet for your vehicle, the easiest place to find the right wire is at the parking light switch. If you'd rather locate the wire under the dash, make sure you don't use one that's tied into a dimmer circuit. Test the wire with your multimeter, and see if the voltage drops when you dim your dash lights.
Since most dash lights connect to the parking light circuits, you can expect the dash lights of your car to flash along with the parking lights. Starter Disable The starter interrupt is a relay, built into most systems we offer, which ties in between the ignition switch and the starter solenoid. The starter solenoid main power feed draws a huge amount of current, so the solenoid feed wire going to the starter cannot be spliced into. The wire that you tie into is the small wire going to the starter solenoid that tells the solenoid to energize when you turn your key to the 'start' position. To verify that you have found the correct wire, test the wires at the steering column to find the one that reads 12 volts only when the starter is cranking (not while the engine is running). Following the instructions supplied with the alarm, splice the starter disable wire (or outboard relay) into this wire.
Valet Switch The valet switch lets you bypass the system when you leave your vehicle for service or valet parking. This means you won't have to give your remote control to anyone. The valet switch is also used for programming the alarm system. The valet switch is usually a simple switch or button that connects to a wire coming from the brain. Mount the switch out of sight so that it won't be obvious to a thief.
Most alarms require that the valet switch be activated only with the alarm disarmed and the key on. Not following the procedure called for in the owner's manual may result in a malfunction. Wire Routing and Terminating Any time you tie into a car's electrical system, maintaining the reliability of the car's electrical system is a big priority.
Here are some tips:. Encase your wiring in protective loom. Solder or crimp every connection, never use wire nuts or simply twist and tape.
Use heat-shrink tubing to protect your splices. If you can't use heat-shrink tubing, tape the splice and secure your tape with a nylon wire tie to help keep the tape in place. Use grommets when running wires through freshly drilled holes. Keep wires away from high heat. Make sure wires do not rub against any sharp metal edges. Use the right size multi-strand copper wire with good quality insulation.
Secure the wiring with nylon wire ties so it won't fall into your pedals or get pinched by other moving parts. Ties also bear the weight of the wire, and this ensures that vibrations won't put too much strain on your terminals. When connecting the main power wire to the battery, install a fuse holder within a few inches of the battery. Use a good quality ring terminal to attach the wire to the battery terminal. Use a star washer when connecting wires to chassis ground, and scrape away any paint or grime that might prevent a good connection to the bare metal and then cover the ground with silicon. If possible, connect ground wires beneath an existing nut and bolt. If a nut and bolt aren't available, use a #10 machine screw with a lock washer.
Run wires through the firewall using a factory-cut hole, if possible. Look at the hood release cable to see if wires can be run alongside it. Some cars will run the release cable between the inner fender well and the fender. In this case, you must remove the inner fender (the plastic guard above the tire).
If you decide to drill your own hole through the firewall, determine that there are no obstructions on the other side of your drilling and don't forget to use a grommet. Soldering Tips.
Strip the plastic insulation back about 1/2' on each wire. Slip a piece of heat-shrink tubing over one wire. Place the two wires parallel but pointing in opposite directions. Wrap the bare wires around each other.
Make sure you have a smooth connection, with no stray wire strands sticking out that could poke through the heat-shrink tubing. Heat up the soldering iron and 'tin' the tip by applying some solder directly to it. This cleans the tip of the iron (the rosin in 'rosin core' solder is a cleansing agent) and makes the process of soldering easier. Heat the wire until it gets hot enough to melt the solder. Touch the solder to the wire and let it melt until it covers the splice. Let the solder cool for about 30 seconds until it's cool to the touch.
Keep the wires still until the solder cools. Finally, slide the heat-shrink tubing over the splice and heat it. A heat gun works best to heat the tubing, but if you're careful, you can also get satisfactory results using a match or butane lighter. Crimping Tips. Always position the seam in a crimp-on connector against the rounded side of the crimp tool. Let the tooth of the tool depress the solid side of the connector opposite the seam.
Check the crimp connection by gently pulling on both wires. A proper connection will not come apart. Multimeter Tips. The negative (black) lead of the multimeter always connects, touches or clips directly to the chassis ground of the car. (Chassis ground is any metal part of the car which is physically common to the point of the car where the negative battery cable connects.).
The positive (red) lead of the multimeter is connected to the part of the circuit being tested. If you poke a hole in the insulation when you probe a wire with the tip of the multimeter, cover the hole with electrical tape. Testing the System If you have a timed dome light on your car which is hooked up to an instant trigger or sensor input, make sure the dome light has been timed out and turned off before testing the system. Crimestopper alarms must be programmed to delay until the light is out. When testing entry through the doors, make sure you test all of the doors. Some vehicle manufacturers use a key-sense wire on the driver's dome light switch (this is the wire that makes your car chime when you've left the key in the ignition).
If you have tied your door entry alarm wire into this key sensing wire, your alarm will only sound when your driver's door is opened. Test each door, one at a time, to make sure each door triggers the alarm. False alarms are usually the result of sensors being set too sensitively. If you experience a lot of false alarms, dial the sensitivity back a bit.
Ford EcoSport facelift and Tata Nexon are the most exciting offerings in the sub-compact SUV segment with impressive styling and useful features. However, being in the same segment they are the arch-rivals and if you are thinking of buying any of the two, it becomes very important to know which one is better.
In terms of styling, looks more matured than the previous version with an aggressive front-end. It has the looks to boast off, which overshadows the premium appeal of the Tata Nexon. Moreover, EcoSport is slightly taller and longer than the Nexon, while Nexon is substantially wider among the two. The updated Ford EcoSport offers a 50mm longer wheelbase than the Tata Nexon.
Mechanically, the 1.5-litre Revotorq diesel engine of the Nexon produces 108 bhp maximum power, which is 9 bhp more than the same capacity diesel engine of the facelift EcoSport. However, the new Ford EcoSport offers two petrol engines - 1.5-litre unit and a 1.0-litre EcoBoost variant, which delivers more power and torque than the Nexon. In terms of price of both the cars, the Ford EcoSport facelift is to be priced between Rs.
Please, do not post your product serial number on public websites and forums such as this one. Autocad 2012 francais 64 bits crack.
7.5 lakh (ex-showroom) to Rs. 10.5 lakh (ex-showroom). On the other hand, the Tata Nexon is priced frugally starting from Rs. 5.85 lakh (ex-showroom) to Rs. 9.44 lakh (ex-showroom). If you look into both the products, they are equally well-designed products and are best in their own way.
The affordable pricing and powerful diesel engine are the advantages of Nexon. But, if your budget allows, the 2017 Ford EcoSport is better overall. Nov 03, 2017. Tata Nexon is the subcompact 4-metre SUV from the Tata Motors, which has created a lot of buzz even before its launch.
I don't expect the Tata Nexon gets a CNG kit and it only offered 6-speed manual transmission. Here I specify some of the, have a look = It is available in both the engine. The petrol variants carry 1.2-litre Revotron which produces 110 bhp of power & 15-17kmpl of mileage while diesel have 4-cylinder 1.5-litre Revotorq engine which makes 110 bhp of power & 21-23kmpl mileage. = 6.5-inch touchscreen infotainment system, automatic climate control, dual front airbags & reverse parking sensors = Three drive modes Eco, City and Sport Sep 12, 2017.
