The passlock II wire colors are yellow, black, and RED / white (not used). *1 The BCM (Body Control Module) is under the driver side dash. *2 If Directed module part #456G is not available, refer to directfax document #1601. On base model trucks the lock wire is lt. blue (-) and unlock wire is white (-). They are in the lt. blue plug at the BCM. *3 On base model trucks the door trigger wires are in the lt. blue plug at the BCM. On 4dr trucks the LR door trigger is lt. blue/black, and the RR is lt. GREEN/ black. They are in the purple plug at the BCM. Use all wires and diode isolate.

Passlock wires are very thin gauge wires coming from the key cylinder. The ones you need are ORANGE / Black and Yellow.
I would suggest using a PLDATA to bypass the passlock though since it makes the install a piece of cake and it only takes a few minutres to install. You should also get a GMDL4 databus interface module. Take a look at them here:
GMDL4
PLDATA
You should definatley get the GMDL4 if not both though. ------------- J Rilla

OK you need to tap that black wire. I thought all pickups and SUVs were ORANGE / Black, but maybe on the 2003 they went to Black.
Didnt your bypass module tell you to hook up a wire to the black passlock ground wire? What bypass module is it?
