2005 jeep liberty blowing fuses for brakes and blinkers after you had trailer wiring put on a little black box is getting hot and the white ground wire is melted?
Whoever put the trailer wiring on either cross wired something or a wire got pinched somewhere. Unplug the trailer and try it. If it still blows, it in on the jeep, probably where the wire is spliced in. If it only does it when the trailer is plugged in , you can disconnect each wire one at a time till you find the one that is shorting out. It is just a process of ellimination. The person that did it should be the one to fix it if that is possible.

Why does your trailer lights go out when you hit the brakes on your f 150?
You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.

How do you ground truck hitch brown wire?
DO NOT GROUND THE BROWN WIRE. It runs your running lights. Ground it and you will blow the fuse - and the lights will stay dark. Ground the white wire. Just put a ring connector on it and put it under a sheetmetal screw on the body of the tow vehicle. Yellow and Green are combination brake and turn signal circuits. I think green is left and yellow is right, but I'm not sure. Blue runs trailer brakes. Red charges the trailer battery. This all assumes that you are using the sort of industry standard colors. I've seen all kinds of screwed up trailer wiring - including all one color. Good luck.
