    Hey everyone, I was working inside the driver's door panel of my '06 SR5 Double Cab and found a rigged up alarm/lock system hooked up to the door lock actuator. Since I bought and programmed new key fobs for the truck as it only came with one key, I decided to strip the entire aftermarket alarm off. While doing so I found this little gem behind the kick plate by the driver's side. I'm assuming it may have something to do with the trailer hitch, mostly because I tried out the 7 pin connector with a tester and there is no power going to it (I made this assumption weeks after I found the cut harness, since most trucks have a relay behind that kick panel that powers the trailer lights. The truck has what I assume is the factory towing package. Any ideas what I'm missing here?harness1.jpg harness2.jpg

    It appears to be the hacked up remains of a trailer brake controller harness.

    So the TBC was sending power to the connector in the back (including lights) or is it another fuse? Does anyone have the wiring diagram for the trailer lights?

    Brake controller has no connection to trailer lights. If you have no trailer tail light power, check fuses in the box under the hood.

    All right, I'll do that tonight. Lets see what comes up.

    UPDATE: There was one blown fuse, but it still would not work, all 3 signals were missing. After messing around with it I climbed under the truck and jiggled every connection and worked myself back. It's working now! I guess I can buy a brake controller now, looks like that's going to be a five minute job.

    Thanks!
