for those of you wanting to install an alarm i found this on one my local boards. (its a pay site otherwise id just post the link)
I put a viper 5000D alarm in my car a few weeks ago so i thought i would shed some light on the subject for those of you "bold" enough to try it, haha. Heres some advice for what wires you will be looking for. i will provide you with what wire does what, polarity and approx location of the wire.
***DISCLAIMER*** These are the wires i used, i am not responsible if there was a mistake made (these are true to the best of my knowledge and have had no problems for a few weeks now so they work for me). just making sure no one can hold me to this.
here we go
"12 volts" Black (+) ignition harness in steering column
"Starter" Black/Blue (+) ignition harness in steering column
"Ignition 1" Blue (+) ignition harness in steering column
"Ignition 2" Black/Red (+) ignition harness in steering column
"Accessory" Black/White (+) ignition harness in steering column
"Power lock" Green/Red (-) module high in drivers kick panel
"Power unlock" Same as above*
*(for power unlock however, it needs a (-) signal through a 1.5k ohm resister)
"Parklights positive" Green/Black (+) driver kick panel*
*(for this wire, it is in a wire harness that has more then one of these colored wires, the one you want is the 5th pin from the "right". it'll be real easy to test if you found the right one, just stick a voltage tester on it and it should light up when you turn on your head light switch up one notch.)
"Door pin" Black/Blue (-) driver kick panel
"Trunk Pin" Red/Green (-) trunk light on left side
"Horn" Black/Red (-) Steering column
Hope this helps.
Cheers
