If this is the newer style body style, there are no fuses for the trailer. They run through a SAM module.

So. I'm not messing with the penske deal more than just swapping a fuse...we pay too much not to have them deal with their own property.
And I don't know trailer wiring to save my soul so I'd rather get them on it so any preexisting problems can be addressed effectively not fixing my 1/2 azzed attempts lolhomeskillet Thanks this. -
Every owner should buy this ...

I hope my mechanic has one. I saved the pigtail to hopefully put a new end on it? I don't know trucks but my DIY life has always had replacement ends for various stuff. It'd be an almost free spare under the bunk...but only if it works lol

Look at the plug at the end of the tractor cord that plugs into the trailer. Not the top one, but the two next to the top one needs a jumper wire to tie the trailer lights circuits together. I pull doubles and when I have a problem with one trailer or the other with clearance lights not working, I simply plug my special plug with the jumper wire into the rear of the rear trailer, and it feeds the circuit that is not working. Just remember to remove plug when dropping trailer. You most likely only pull one trailer, so the jumper wire goes in the end of the tractor light cord.
