Hi I am in the process of hooking up an alarm on my 1992 z24 and have difficulty finding the door trigger wires and also hooking up the power locks to work by using the remote. Can anyone suggest any ideas
I have looked on the door lock page I am on just not to sure which one my car is. Could anyone help?

The door locks are Type A (+). Your alarm system must be set to output a positive 12 Volt signal to the
door lock and unlock output. Some units only output a (-) signal and relays must be used to convert it
to the required (+) 12 volt signal the car needs. Here is a link to the relay wiring if (-) to (+)
conversion is needed : https://www.the12volt.com/doorlocks/page3.asp#3wp
Here is the lock info from Bulldog :
POWER LOCK LIGHT BLUE (TYPE A) IN DRIVERS KICK PANEL
POWER UNLOCK BLACK (TYPE A) IN DRIVERS KICK PANEL
Here is the door trigger info :
On the 2-Door vehicle at the DRIVERS door pin switch use the LT.GREEN/ BLACK (-), for
the PASSENGER door use the LIGHT BLUE. Use the same wires for the 4-Door vehicles
but to cover the 2 rear doors you must tie in right at the pin switch at each door and
DIODE ISOLATE all 4 wires when connecting to an ALARM SYSTEM.

Thank you so much! I will defiantly need to put some relays on the doors. It is the 2 door model. One quick question were would I get the 12v from and what amp fuse would I put on it?

A 10 Amp fuse should be OK. If you don't have the relays already, look for a DEI 451M door lock module. They can be had for about $10, and have evertything in a small, neat package, including the fuse & holder. The 451M install guide is available in the Downloads section for your review.

most likely not. You will probably have to either find a local DEI dealer / stereo shop that may have one or you will have to order it online.

Or if you were in the UK you would be two Omron 10amp pcb relays for £2 plus a pair of diodes for 20p = $3.30. I refuse to buy 451s or the DEI 8166 made up relays, too expensive!
The UK trade price is about $10.

It is a compustar 1wam(as) cm3000-vf. I have tried hooking up the alarm with the relays. Like it shows in the 3 wire positive way and no luck.

On your install instructions does it have a connector #4 with a Blue (+) lock wire and a Bule/Black (-) unlock wire? If so you should be able to connect these wires to your lock and unlock wires on your vehicle. Bulldog wiring shows these as Lock, Light Blue and Unlock as Black.
As always test and verify with a DMM.

Kreg possibly made a typo, ref. + - meaning only -. I haven't looked but those are the two he meant, feed them to the relays.
