my newest damn problem

So all was going good after my fuel pump install....
then a turn signal goes out....i get home and as i pull in all my back half lights go out.
no brake lights, no turn signals no parking lights. the front half work. just nothing bed back. and when i step on the damn brakes my parking lights go on. it was dark and i haven't looked around yet, but what the hell could cause that? bad grounds??? or maybe i pinched some wires when put the bed back down?? none of the wires where even close to the bed rails ??!! grrrr

Yeah it sounds like a possible short caused by a pinch. Do you have any blown fuses?

You lift the bed up or take it completely off? The harness to the taillights has a connector right at the end of the driver's side frame rail, flat 4 pin connector that sort of (but not exactly) looks like a trailer connector. Check it, and check the ground that screws to the frame back there, comes from the rear harness section between the taillights.

i lifted the bed from the drivers side. i saw that connector and it looks like my trailor wiring comes off of that. i'll check that first. i unbolted all the driver side bed bolts, then loosened almost all the way the passenger side bolts and lifted the bed using 2 jacks and jack stands. the wiring looked to come down the passenger side frame rail and then split out along the back frame brace to the tail lights on the drivers side. someone suggested me that there was a ground from the bed to the frame that could have been severed, though i didn't think any of the lighting was grounded to the bed. i'll have to check again to be sure.

Ground the back half...sounds like you forget to screw the ground back into the frame on the back wiring...just as someother guy wrote.

You should have found two factory grounds. One off the filler neck assembly, and that's just to ground the filler neck for static electricity. The other comes from the harness between the taillights and usually is attached on the very rear frame crossmember, don't confuse it with the ground wire that should be on your trailer harness too. Sometimes when people put in the trailer harness they ground it to the same spot, sometimes they don't. So in other words two factory and one added from your trailer harness.

you sir are indeed correct. after digging around the frame i noticed a questionable black wire just hanging around. the end was cut clean but i could find NO bolt and terminal loop (wire crimp) in the area that the wire could have led to. the truck was trailor wired before i got it. they had a adapter on the factory harness and then 2 wires for the brake controler wired in. so i found a nice spot and grounded it. and walla they worked again. NOW my dash lights don't work!!! i just noticed it when it got dark!!! ugh electrical gremlins!!!! or ninja's as some one else called em on here lol. i think maybe a fuse is loose or somethin, cause i did rummage through the fuse pannel.

i'll check in the mornin.

eh i went outside and jiggled the fuses, and poof. it works. problem solved? for now ha

They don't call 'em shitboxes for nothing...

better then a rustbox. way to oxidize the planet!!!
