From 1998 Chevrolet Tahoe Alarm Information, the doors are positive trigger. Door Lock is Light Blue and located "Above Accelerator Pedal at Factory Relays" - run the blue wire from the door lock harness (3-pin connector) to this; Door Unlock is White - run the green wire to this.

Before running any wires, put a DMM from these wires to 12V (red -> 12V, black to test wire). DMM should read 12V most of the time, dropping to 0 when you press the lock (or unlock) button. If you don't see this behavior on the wires you're hooking up to, don't hook things up to them!

Blue (-) status output on the relay pack is ground when remote start active. (Look at the last page of the manual)

Hope this helps,

Me
