Fuse Blows on T-One Wiring Harness When Hooked Up to a Trailer

Question:

I install the hitch and this wiring kit. Everything went smooth, but my fuse keep sparking and getting blown. I connect it to the positive terminal and follow the video exactly. The trailer light will work for a few secs and then the fuse will blow.. any advice?

This sounds like you may have a pinched wire.

Look at the green, yellow, and brown wires that are ran through your vehicle and check for any areas where the wires are pinched and touching the metal of your vehicle. If they are, this will cause the wire to be grounded out, which in turn will cause them to short.

Replace the fuses and test each function without the trailer hooked up. Use your right blinker to see if it's the green wire. Use your left blinker to see if it's the yellow wire. Turn on your headlights to see if it's the brown wire. This will help you determine which wire you're looking for the problem on.
