1st Alarm Install Compustar in Cavalier

Hi guys Im new here and hopefully you can help me along the way with questions and any problems I run into.  I bought a Compustar 2WSS-AS alarm and will be installing it inot a 2004 Chevy Cavalier LS Sport Coupe which has an OEM alarm and keyless entry.  I would have a local shop do it but they want $400 for the install.

This will be my first alarm install.  My knowledge of wiring is installing HU's and I did uninstall my basic Python alarm out of my old 97 Cavlier. No power locks or anything. Im a DIY . 1)saves alot of money 2)learn alot 3)you know things are done right and secure.  But alarms are new to me so I want to make sure im doing things right no matter how long it takes me.  I've been doing alot of searching to see what I can find and learn.

I will not be hooking up the remote starter for the car because I really dont need it and I dont want to hassle with it.  So for now I'll leave it be.  Now on to my questions.  Is there any special bypass I will need (remember not installing remote start)?  I heard i might need one for my power locks or something? Also will I need any relays?  If I need any of these things can you point me to which model I will need.

Thanks Ryans

Be sure to follow instructions for Lock / UNLock
if your vehicle does NOT have Factory Keyless Entry it will require 2 SPDT Relays and wire as 5 Wire Reversal.
Otherwise it is ( + ) pulse

Try:

Power Lock	lt. blue	+	BCM, purple plug, pin A4	On vehicles without keyless entry, the door lock wires are just located in either kick panel. They are 5wi (Type C), and mastered from the passenger door lock switch.","CHEVROLET, CAVALIER, 2004, Power Lock");' href="https://www.directechs.com/directwire/wire_body.asp?action=select&yr=5583&product=Remote Start#">

I installed the same compustar alarm on my 2000 Honda Civic and I was told that I had to hook up the remote start for the system to work correctly.  I have not had any problems except that the antenna I was sold was faulty and only worked in weather below 40%. But I sent it back and got a new antenna and it works great.  It really is not that much work to hook the remote start since you need to feed the siren wires and hood senser wire through to the engine comparment anyway.  While you are doing that you just need to feed through the tack wire at the same time.  Good Luck!

Ok i finally got my alarm today and i've been matching up my wiring connections from my alarm to car wiring.  First off what does BCM stand for? 

Now i have some wires that i have no idea to what wire to connect them to in my car.  

yellow/black wire on the main wiring harness thats coming out of the starter kill relay?

black wire from - status output

WHITE/ black wire from - 2nd accessory output

violet/black - trunk trigger input aka trunk sensing(connect to - trunck/hatch pin or - trunck/hatch release?)

RED / white -door trigger input

red + door trigger input (not use this one?)

violet/white - trunk ouput aka trunk unlock

ORANGE / black -2nd pulse unlock aka 2nd unlock output (says use this wire and isolate drivers door actuator from rest of doors.  how do i do this and where is the actuator? is it the door trigger thing using the diodes?)

blue - unlock output (+power unlock or 5wi unlock motor?)

blue/black - lock output (+ power lock or 5wi lock motor?)

orange -rearm output

ORANGE / white -disarm output

violet -dome light output (says automatic transmission only. dome light is turned on for 1min after unlock.  I have a manual does that mean dont hook it up?)

Aux 1 and Aux 2 (do i just leave alone)

All these wires I dont know what to hook up to if i even need to hook up some of them.  So can you guys help me out and let me know what i should hook them up to thanks.  I really appreciate all the help.

Not totally familiar with the Compustar 2WSS-AS, but some of the info you have should go like this:

BCM = Body Control Module

VIOLET / Black =

RED / White =  ( Diode Isolate )

RED = XXXX

VIOLET / White = ( Relay needed to convert to 12 volts Positive )

ORANGE / Black =  ( Relay needed to convert to convert Driver Unlock wire )

BLUE & BLUE / Black = ( Reversal Rest At Ground Door Locks )

ORANGE = XXXX
ORANGE / White = XXXX

VIOLET = ??? Not sure what Manual Trans has to do with it either )

I have everything working right but i have a few questions on the door lock.  As quted abobe I DO have factory keyless entry.  So all i need to to is hook the [power lock lt.blue, to blue + lock output and power unlock white, to blue/black -lock output]?  Blue doubles as a -unlock output and blue/black doubles as a +unlock output (info. from wiring installation manual).

Also I have a question on the ORANGE / black (drivers door proirity unlock) wire from the alarm.  Do i convert the polarity with a relay?  If so which way - to + or + to -.  Also does this wire connect to the my Unlock motor (tan) from my car?   Thanks

I just went out side to see what the wires were reading on the relay.  On the lock relay  87,86, and 85 show 12 volts and when i hit lock 85 jumps up a little in volts from 11....V to 12...V.  On the unlock relay 87,86, and 85 show 12v.  When i hit unlock 86 goes from 12v to 0 then back up. 

Its fried cuz the unlock gets 12v when i get the unlock button and the lock does nothing.  Is there another wire i can use for the lock?  Also if i diode isolate the unlock and lock will that prevent the output from frying out?  Which direction do i put the diode in?

Thanks guys
