Sorry if this is a repeat topic. I have a 1967
Overlander with no power to the rear lights: Brake/turn signal/running lights/clearance lights/license plate/backup. Front three and two front side clearance lights as well as brakes and blue 12 volt
power to interior lights work fine. It was my Dad's and sat for a long while, 15 years, before my family decided to get it running this year. Had axels/brakes checked and repacked. New Tires/Wheels. Towed great from South Dakota to Illinois but I had to rig up a set of rear lights for brakes and turn signals for trip off 40 feet of wire run from TV. (I have a 4 flat and 7 blade receiver so I was able to run the temporary lights of 4 flat and brakes off standard 7 blade.) Didn't worry about the clearance lights and only ran in daylight. So I have pulled the access panel at front underside and confirmed, using 12 volt
converter and jumper wires as power, that no power is going to rear side clearance lights or any lights on the rear. So my question: what is the wiring path for these rear lights? Is it behind the finished wall board? Is in in the floor? Is there a harness point somewhere accessible in the after part of the trailer to check for power/continuity? Hate to run with temp lights on vacation but don't want to go digging for more problems when I don't know what I am doing. Any thoughts would be helpful.
