I would make splices with crimp butt connectors filled with electrical grease and covered with heat shrink.

The quote above or soldered and use heat shrink tubing to seal. The scotch guard connectors often fail due to being unsealed. Galvanic corrosion is usually the cause.

I usually spray the TT & TV vehicle power plug/receptacle with WD-40 at the beginning of the season. Occasionally you may need to compress the contacts on the TT plug as they will spread and loose the ability to make a good tight electrical connection.

Good luck with this. I did many of things that you have done including replacing the plug from the trailer with the recommended one, took the new trailer to the dealer twice, took the new Chevy truck to the dealer twice, and after all that, I still received the message. I sold the truck and bought a Ford, it doesn't do it anymore!

Junk wiring on the trailer.

Typical spot for intermittent wiring faults is the wires that run INSIDE the axle tubes. Those wires are loose inside the tube which leads to chaffed insulation which leads to intermittent shorts in the wiring.

The moving wires also can eventually break leading to loss of brakes..

Best bet is to scrap the existing brake wiring on the trailer and run NEW wire and wire tie the wires to the OUTSIDE of the axle tubes.

Replacing the wire is the easiest and fastest way to fix intermittent issues.

You can also use that as a upgrade route, move up a couple of wire gauge sizes and pickup better braking..


This is what I found to be the answer to the "check trailer wiring" message. I chased all the other options for a long time. The wires inside my axle tubes had the insulation worn through. I put new wires on the outside of the axle tube. Problem solved.
