Nolan that's a great way to troubleshoot but it could prove to be expensive.
(START YOUR TRUCK ON FIRE)Do you think it would have been easier to ask
someone or look at service manual for you truck. As for the other guy I
would look for chaffing in the wiring harness. Also isolate the front from
the back. Nolan just kidding

itself surprized me, because I wouldn't have expected it. My truck has
suffered from intermittent rear taillights for months, and blowing fuses. I
could never find what the darn problem was. Then I started blowing fuses
rapidly. Did it in the dark on me once, and I had to try using a paperclip
to jumper the fuse. When that glowed red and caught the fuse box on fire, I
figured the problem was getting a bit more serious, so I drove in the dark
without lights that morning. In disgust I finally shoved a heavy jumper in
there and stood back to watch. Once the smoke started rolling, I knew where
to look.

Not so heavy as a wire solidly grounded out, but heavy enough to screw
around with my lights and occassionally blow the fuse. Not untill the
damage got bad enough to start a fire was I able to locate it.

BUT, you do have the capability for damaged wires, which would do the same
thing. I would start looking at that end of the lighting circuit that has
had problems with poor illumination or bulb failures. I think you're going
to find a wire that is lightly shorted to ground. In your case, that's the
passenger side wires. You may also have burned up some wires in the
harness, and have them shorting to each other.
