it starts at the rear lower latch, then runs over to the left tail light, then forward to the main harness connector at the rear seat, then forward and down to the floor up the left side to the fuse box.

It remains the same color the entire way.

 

My sub box came with a light in it. At first, I didn't want to use it for obvious reasons, but i used it to replace the trunk light. was that even relavent? oh well.... If you can't find the wire, just make a new relay and put a switch on the inside lip of the trunk so it pushes when the trunk closes. That way, you can get more power and use more lights.
