I am installing a aftermarket remote starter in my 2000 Bravada and am having trouble finding the last necessary wire!

This remote starter system works with the OEM alarm system so, suposidly, I can use my GM key fobs.

I am triing to find a "negative lock signal wire of the factory system". According to the directions I need to connect to this wire to supply the remote start system with the "start activation input, OEM interface".

If it helps here is the full description out of the installation book. "[alternate OEM interface] This mode allows the system to remote start or stop when 3 successive negative pulses are sent to the input wire. Connect the green input wire to the negative lock signal wire of the factory system. If your factory OEM system does not have this type of signal, then a relay is required."

THANKS!!
