i lost it on the truck,
my truck has the factory plug for the brake controller so i hookep it up (using a prodigy controller and hardness) but it had no power at all, so I checked for power on the connector and no juice on any of the wires. so my father in law run a wire for power, we tried and the brake controller worked, he also run a separete inline fuse for just in case. after we thought we were done I back up to hook to my trailer and that's when we notice that I had no brakes, tried the signals and don't work either, tried the flashers same deal, i got working only the headlights, low beam and high beam, driving tail lights and third brake light, interior lights are good too. like i said we checked every fuse, took one of his relays out of his truck and tried on mine and still nothing, under the steering colum there a switch box, we changed it that too with his and nothing. check the fuse connectors on the fuse box for power and they all got juice too.
please let me know if you need any more info, as you can see a\i'm not that good with electrical crap so i'll try to answer questions to the best of my knowledge.
I jsut got the truck about a month ago and it didn't come with a manual.
