OK here's what I've got:

J1 pin 1-red, pin 2-orange, pin 3-yellow, pin 4-ground, pin 5-pink, pin 6-pink/white.

J2 pin 1-blue @ switch, pin 2-White with relay, pin 3-not used, pin 4-not used, pin 5-to wire at purple plug in BCM, pin 6-not used, pin 7-not used, pin 8-to bypass module, pin 9-at fuse panel, pin 10-at fuse panel, pin 11-black, pin 12-white at brake switch, pin 13-white @ECM, pin 14- hood pin switch.

Bypass module- "true ignition" to pink(same as pin 5 on J1)

the only changes I made after it was working were the second ignition wire(wasn't hooked up)and I moved the true ignition wire from bypass module from yellow wire to pink.

Thanks

Here is what I found to be different about your hook ups:

PINK/WHITE ( P6 ) : Double check to make sure this is a constant wire with a DMM

BLUE (J2 Pin 1 ) This BLUE wire that you attached the WHITE wire to , did you test this for 12 volts when the lights are turned on ? I have this color to be a BROWN wire at the lt. blue plug at BCM ( The BCM is located behind the drivers side of the dash. The plugs on the BCM face towards the rear of the vehicle. The parking lights are in pin A5 and the headlights are in pin A11. )

PURPLE ( J2 Pin 5 ) : This is your disarm (-) output that should be going to a LIGHT GREEN wire in the driver's kick panel. It is also found in the PURPLE PLUG ( not the PURPLE wire ) in the BCM. I think this is your problem here as this affects parts of the BCM that controls various other functions of the interior.
