    Hopkins 4 pin tester

    It’s a GMC Canyon. I checked the fuses, they’re still good. At the bed of the truck the wires run into a 7pin and 4 pin adapter combo, that comes out next to the license plate. Would that be the adapter box? This is the part I am talking about. I tested the 4 pins with another tester today...

    Hopkins 4 pin tester

    I moved the ground from the tongue near the hitch, to the main frame. I was losing connection at the pivot point and couldn’t get a good ground up front. I spliced in more ground wire ran it to the front of the main frame and got good turn and break lights.

    Hopkins 4 pin tester

    Sorry for the bad photo quality, but as you can see this is the tester with the turn signals on, but not the tail, I did have my truck lights on also.

    Hopkins 4 pin tester

    I’ve been having problems wiring my tilt Jon boat trailer. I finally learned I needed to run the ground to the actual frame and not the front.

    Wiring Problem on Tilt trailer

    There’s not, but I ran my ground all the way back to the stationary part and that helped with the break lights, and turn signals. The running lights and the license plate light still do not work.

    Wiring Problem on Tilt trailer

    My truck has both a 7 pin and a 4 pin connector on it. The lights on the trailer uses the 4 pin, do I need to get a 7 to a 4 and do it that way?

    Wiring Problem on Tilt trailer

    I just tried this, it helped some of my problem but not all. I now have good brake lights and turn signals on both lights. But I still don’t have running lights or the license plate light.

    Wiring Problem on Tilt trailer

    Hello, I have a jon boat trailer that tilts. It needed rewired because the guy before me who had it did not have it wired. I’ve spent hours trying to get it right, making sure the grounds are touching bare metal and good connections on everything. The lights are still dim after everything I try...
