My tail lights won't come on, but rear side parking lights, licence plate lights and stop lights all come on. Somewhere I found that there has to be a yellow sensor switch that can be bypassed. Tried searching both left and right sides of the trunk but no luck. Any ideas where exactly is this switch on 1993 Camry, or any wiring diagrams??? Thanks in Advance.
The sensor is behind the carpeted covering. But first, check the wiring at the trunk hinge - flexing can cause a wire to break.
I had the same problem in my 90 camry. I found the little yellow box on the left side of the trunk(on left wall) under the rug or plastic. I shorted it out when I put the wrong bulb in. It was all melted and black inside. I went to the junkyard and picked one up for ten bucks and problem solved. Good luck.
