PIV Rear Couresty Light

Did you try turning on the acc button on the dash? I know they are not usually wired to it, but it may be worth a try.

It does not come on with the ACC switch. BCB wires are there to the light, just not sure where they are ran from so I can trace back. Do they feed of the block n in back normally?

If you have a vom meter, dis-connect the battery and check for continuity from the battery hot wire to the lights hot wire with and without the master power switch on, and from the negative battery cable to the lights ground wire, and post your results and let me know the ohms readings that you get, if that is possible.
