The Hopkins Plug-in Simple Brake Wiring Adapter #HM47795 should have the red wire run to the pin right next to the blue wire closest to the clip side of the connector. See the picture I attached. The blue wire you found under the hood of your truck…

On a 1999 Chevy C3500 there will NOT be a brake controller port to plug in a brake controller. The brake controller has to be hardwired into the truck. Chevy did not start putting in a port until they switched the trucks from C or K to Silverado.…

The first thing to check is the connectors to make sure there is no corrosion present. That can cause a variety of problems. If that checks out you will need to do some other testing. You can sever the blue wire about 4 to 6 inches from the back of…

There are a few things that can cause the brakes to lock up on a trailer. First, disconnect the trailer from the vehicle. Then use a circuit tester like #PTW2979 if needed to test the connector on the vehicle. Have someone sit in the truck and run…

It sounds like the purpose of getting the air helper spring would be to counteract the 1 inch compression you're getting in your rear suspension caused by the pin weight of your 5th wheel. If that's the case, I believe that the AirLift 5000…
