Back clearance lights

[dkeffer]

Problem: Front clearance lights work but back clearance lights don't.
I took the plate off the bottom where the wires junction. I located a light green wire where 3 wires came together. I put the feed wire to one of them and the front clearance lights came on. The other wire when connected doesn't light the back. We have had some mouse damage so this wire needs replaced. Can I pull a new wire? Which tail light does it go to first? I don't want to guess, and drill out more rivets then I need to pull it out. I want to pull all new wires to the back while I'm doing it. The trailer I'm working on is a 1968 Safari. Thank You

Unless you are willing to remove the interior skin I doubt you are going to PULL new wires. The wire run through the ceiling and pass through several ribs.

I would remove one of the rear marker lights and check the wire color feeding it. Then try and find that wire forward and connect FUSED power to it as a test.

Remember you will have to reattach the marker light for the test as the light body is the ground path to the trailer skin.
