I'm getting a "Check Brake Wiring" error message in my truck. Before I take the trailer in for repair, any recommendations for a RV side wiring tester?

Often that message will lead to a problem with the connection at the truck. It can be on the truck side or the trailer side, just clean the connectors and plug them in and out a number of times, then see if the message reappears. If you find the connection is good the issue can be in the wiring to the brakes and possibly inside a brake.

Does the message say, check right or left brake light?
Mine has been swapping back and forth between the two messages. It’s been checked by KZ service and nothing wrong with fifthwheel wiring. My truck is a 2022 Silverado, Duramax. I checked wiring, okay. Because they use LED lights now it does not take the same amount of amperage as when we had filament lights.
When I get a warning, I check my lights, everything works fine. I reset my warning on dash.
Etrailer has an adaptor for 2021 and earlier but didn’t have the adaptor for 2022 when I checked. They might now.
I just checked etrailer, here’s the part number, 7-Way Trailer Adapter for Towing Trailers with LED Lights
Item # C57003

I've had two brake wires cut by the "LIBO" wire taps at the brake back. Terrible design. They nick the wires, and with time and vibration, the wires break at the nick.
