[wd 69]

Well, here is something else I noticed: When I pull out the light switch, I get both elements lit in the tail light bulbs. Same thing when I step on the brake (with the lights off). So when I break with the lights on - nothing gets brighter. Obviously, I should have the two elements separate. One for brakes and blinkers, and one for tail lights. I got under the bed and pulled the plug in the wiring harness running back toward the cab and rang them out. Everything looked shorted. Went up under the dash and pulled the semi-circular plug there. Rang it out.
The female end runs back to the tail lights, right? If I am right about that - it did ring shorted. Thing is, I went back to the plug under the bed and even after breaking the connection (semi-circular plug) under the dash - the plug under the bed by the spare still rang shorted. Circuit must be shorted in the harness under the bed then, right?
