Additional Info:
This vehicle is equipped with PATS (Passive Anti-Theft System). Use Commando module TransMod to over-ride during remote start. [1] The GEM module is to the left of the steering column. [2] The headlights are high current negative. Must use a relay. [3]This wire controls the door ajar indicator on the dash, must cut the wire and diode isolate it from the instrument cluster. Can also use individual negative door trigger wires in the 26 pin plug at the GEM. They are: yellow/black (LF), gray/red (RF), lt. green/yellow(LR), and pink/lt. blue(RR). [4] On the sedans use black/pink (-) at the light in the trunk. On the wagons use white/purple (-) in the 26 pin plug at the GEM. [5] With keyless entry it is purple/yellow (-) at the switch. Without keyless entry it is gray/red (+) at the switch. On the wagon, to unlock just the rear hatch use yellow/lt. green (-) in the 26 pin plug at the GEM. [6] The PCM is on the passenger side firewall under the hood. [7] The rear control unit is on the left side of the trunk.
