I got new everything when I was putting that all back together and spraying the inside of the trunk. The wiring harness is metal alloy even. Suddenly out of nowhere my left side brake/turn signal went out. Also have a new turn signal switch and harness. I already checked and even swapped out the bulb just in case it was in the bulb. Not the bulb. So I pull the push on cap end back off and it just has this disk thing in there. How do I test the thing? I don't think I even understand how that works. It isn't ground because the running light element burns fine. I think I'm starting to understand why places sell these pig tails. Since my brake light switch is just hanging at the moment I thought I would just wait until I get the kit in and fix it back right so then can see if the brake light part of the circuit it working. That would move the problem back to somewhere under the UGH, contortion dash. Guess I will be removing the driver side seat,,,,,,, again.
