Anyone ever experience this before?

I've got everything BUT tail lights... and I've got everything (including tail lights) on the trailer??!?!?

Happened after I hooked up a trailer. Lights are full LEDs, not just bulbs. All fuses are good.

Which wire is the hot wire for the tail lights (in the main harness going from the rear end of the truck to the front)?

Thank you.

Been pulling a trailer lately?

 

Yes, it happened right after I hooked up a snowmobile trailer.

Also should mention, the lights are LEDs. I have brake, turn and stop, but no tail.

 

The wire should be white / yellow, it is on pin 1 of the tail light assembley,
then pin 6 of connector C135 which I believe is on the firewall on the driver side,
it connects to pin 8 on connector C9 right on the "Totally Integrated Power Module" (under the fuse box)
Good luck man.

 

The LED replacement bulbs are horrible, they burn out with any kind of spike. I just got rid of mine and put the incandescent bulbs back in.

 

They are full LED tail lights, not just the bulbs.

 

Come on, someone has to have had this problem before... HELP! I can't drive at night!

 

Found problem, thanks guys!

(Broken/corroded wire on left side down in the wiring harness, and the right side was a broken/corroded wire in the LED assembly.

Darn NY salt!

 

i am having this exact problem. where exactly did you find the break? pics would be awesome. thanks.
