I’m working on my rear lights. The brake light works. The rear side marker light does not have any power. I think it is powered from the fuse box under the rear seat. Can you confirm? I also think the power wire is purple. Can you also confirm?

Okay, so as far as i know the main fuse box is located in the front left side down by the parking brake pedal. Also, there should be one under the hood in the engine bay passenger side it's a black plastic box, and maybe more relays and a few fuses in behind the glove box. hope this helps, good luck.

You are correct, it is powered by the purple wire and there is a fuse for it located in the rear fuse panel under the left rear of the seat. Please check the RH PARK fuse.
