well, the socket pig tails are not side oriented... i went out and swapped them, and it did the same thing. the drivers side is just not burning hot enough, and the reverse lights are still coming on.

but i did find out, and confirmed, that when the the trailer harness is unplugged and the tail lights are plugged in without the trailer harness, the lights work as they should, without the reverse lights coming on.

im at a huge loss, and dont know what to do... the trailer harness is unmolested, and is in great shape. so its not that.

edit... also, i can take either reverse light out, doesnt matter which side, and they no longer are on with the brakes. however if both reverse bulbs are in, and you take the drivers side brake/turn bulb out, the reverse lights go out as well, but only when the trailer harness is connected.

Your problem IS in the trailer harness. Check all wires, to see if any are shorted. (which is what it sounds like.....)

Trailer harness is fine... it was pulled off my buddys daily driver and he never had any problems... so the problem is my truck. Somewhere after the trailer harness. However... curiosity strikes again.. 3157 bulbs in the rear and 3157a in the front right?

If it works fine without the trailer harness plugged in, and doesn't work with it...... that tells me the harness is either not correct for your truck, or, the harness has an issue.

trailer harness is the same from 98-04. its the exact same harness that i had before. the harness is perfectly fine. the only thing i can think of, is that maybe the relay in the harness is bad, but it was working fine when i pulled it off my buddys truck. so therefore, its not the harness, its something on my truck.

im gonna try to get to the junk yard tomorrow and get the tail light sockets, and then go from there.

think i may have found a solution.... http://www.ramforumz.com/showthread.php?t=91573&page=2

anyone else?

Short somewhere.
Electrical probs are the worst!

so ive come to the conclusion, my truck is cursed... i fixed all the grounds i could find dealing with the rear lighting.

however... been thinking about this. could the multifunction switch be doing it? the wipers have been acting funny lately, getting stuck halfway up the windshield and such.

so im thinking its something within that area.

also, could it be the CTM? ive had that though bouncing around too.

wow.... i feel loved! hey you, zman, and dhvaughn have been the only real helps here.

im thinking about just throwing parts at it, and going from there. my next check/part replacement will be the nss, and to check the wiring, and go from there.
