93 MGM Door Lock wires for alarm system

[ysmlee]

I need some help locating the door lock wire to hook into an alarm system/remote starter in my 93 MGM. I am being told that the door lock wires are Pink/Yellow and Pink/Light Green located in the Driver's side kick panel. There are a lot of wires down there and could not find the Pink/Light Green. I did find a Pink/Yellow and another pink with a stripe on it.
Using two 30 amp relays, I hook these wires up and all I controlled was the left rear door locks.
Can anybody help me to find the main door lock wires I can hook my alarm into so I can control all the door locks.

How are you hooking up to this car "Reverse Polarity" or Negative Trigger???????

Found the problem.
The correct wires are connected between the door lock switches in the front doors. The wires routed through the doors across the IP. It was very difficult to find in the left kick panel area so I went to the passenger side behind the glovebox to locate the wires. Not really easy but much easier than the driver side.

I wired it up as reverse polarity as Alarmtek Auto Security suggested (which I paid $5 for the info). It did not work. I thought I had the wrong wires again so I recontacted Alarmtek and they again gave me the basic info including the wiring diagram for a reverse polarity system. I checked everything and found out thath the door lock system on my 93 MGM w/Keyless Entry is 3-wire negative system (after 2 relays I did not need and 4 hours of work).
I unhooked the 2 relays and just wired the two negative outputs from the alarm to the lock/unlock wires and it works just fine.

These cars come with two door lock systems as you may now know. Reverse polarity or if you have a factory keyless system they are negative trigger. They are bunched in a thick wiring harness behind the glovebox, you also could of tapped onto the two wires right at the keyless module. Too bad I didn't see your post sooner i have installed a crap load of alarm/starters in these cars. Look at the bright side at least the car wasn't a 96 and newer with the lighting control module and no tach output.

Thanks Reekor.
Next time I will be sure to post before I waste too much of my time.
