5.4 ltr? if so i believe you have too add a relay underhood. it has a spot for it you just plug it in..

That's what I had to do too on mine, simple enough especially if you have the owners manual...

yea either a relay or fuse, kinda dumb question but is the wiring for your trailer brakes in the proper spot? i had mine redone when i ripped the plug off in the mountains, and the guy put the wire for the trailer brakes to the lights and the left signal was the right and the right was the left, when my lights turned on the brakes locked up

ya, test the plug and check that it is hooked up all correct.

its all hooked up according to the diagram on the cover so i guess its gotta be the relay, is there any way to check the relay . fuses are all good

pull the relay off, and run a wire for the ground to the ground on the relay and then run a wire off your batt to the power on the relay, if it clicks your in business, if not then you need a new one,
