Notes:
NOTE:  This vehicle has the PATS (passive anti-theft system) installed.  It must be bypassed when adding a remote start module.     *1 The door locks are positive trigger if equipped with factory keyless entry, and are 5 wire on all other models.   *2 The LCM is located to the passenger side of the steering column.  The harness is accessable between the steering column and the LCM.   *3 There is a dk. blue for the drivers door and BLACK/ orange for the other three doors.  Use both wires and diode isolate each one.   *4 The PCM is located under the hood to the drivers side of the brake master cylinder.  *5 The wiper motor is located just above the brake master cylinder.

Many thanks, Jeff.  This will make my wife very happy when I complete this install.  Do you think I can pop the doors from the pnk/yel and pnk/grn wires or do I have to go into the door harness to do it?

you should find these wires also in the harness wraped in black tape in the drivers kick panel and not have to go into the door or boot
