From FSM here is the location description: I have not looked for it..
Behind Right hand side of I/P-near the rear of I/P compartment.
If that means interior passenger compartment under seat is my guess, but why do i get the feeling it is in the trunk?
Anyways on the pin listings I don see cruise light or anything like that mentioned under the BCM. Closest mention is the multifunction chime control.
Here is the cruise schematic if that helps...If I get a second in between my long shifts, I will dig further & see what I can find on the dash cruise light. I get the feeling it can be programmed on as a test ....with a tech 2 scanner.
