New Guy - 1st post here - Was referred from a Car audio Forum.

1995 Chevy K2500 Suburban
Working on this Compustar alarm install - Just need to know what factory Door lock/unlock relay wires to splice into. I found them (5ea wires), and this is what they read in this order:
Lock, Unlock, Rest.
White .7, 12, 0
Tan .7, 12, 0
Pink 12, 12, 14
Grey 12.5, .9, 0
Blue 13.25, .81, 0

The Alarm has (-)250mA Unlock and Lock outputs - Thanks, Pat

I looked a that too - but this chevy relay only has a molded box with five wires coming out of it - I have no option of running new wires.. I really just need to know the wires to tap into to make the new alarm happy - Thanks for the reply man, Pat

Go to the drivers kick. Find the lt.blue, and the white. Lock is blue, unlock is white. Test to be sure you have the correct wires. Wire 2 relays for (POS)+ pulse, and solder them to the wires listed.

I totally forgot to post that this suburban already has factory keyless entry - That's what the relays I was talking about are for. I already hooked the alarm to the factory wires in the drivers kick, and it wouldn't lock or unlock the doors, but everything else on the alarm worked, and the factory keyless still worked also. It's crazy... Thanks again, Pat
