2004 GMC Savana passlock prob.

Im having trouble with the colors for the passlock bypassing, I see 2 yellow wires, and a black wire, but which of the 2 yellow wires is it? How does this passlock work?, Im asking because I made a copy of the original key (all metal) and still starts the van with no problem, is the resistor even in the key?. When I try to remote start it a "SECURITY" light starts flashing,Van cranks but shuts off after light starts flashing. Any help would be greatly appreciated, Thanks indvanced.

U will have to Meter wires or follow them up to Ignition Switch

I would rather use the OMEGA - DB-PASS-23A  OR  IB-PLXR  so you don't have to cut Factory wires

Here is som info on PASS System:
