Checked the rear parking lights tonight and they started working. I decided to remove the street side tail lamp to get access to the wiring. It all appears to run through here. I removed the tape from the factory splice. Some of the wires were a little tarnished with black oxidation. I’m guessing just my moving them around hit a bad spot. I stripped it back to a clean spot, soldered and re-taped.
Lesson: Clean up the factory splices while you’re in there the first time.by
