Question:

2011 keystone 5th wheel!!!! I am getting the SH code on my brake controller, if the blue wire runs all the way to the brake assembly do you have to take the wheel and hub off to find it?

The wiring for the Trailer Brakes # AKEBRK-35-SA enter through the back of the brake assemblies for the magnet. To get to the magnet you will need to remove the hub but you can perform your tests on the back side where the wiring connects to the brakes. Your wiring should all connect in a Junction Box # 38656. This is also a great point to check the wiring before it heads back to the axle to determine if the issue is with either the trailer connector or connection on your tow vehicle. With the SH error being a sign of a short on the brake wire for the Controller # 90885 you will want to follow the wiring looking for any signs of a point the wiring may have become pinched or worn through. I have linked some articles below you can use to test your magnets and check the wiring as well for an additional resource.
