Just picked up an 07 XLT with the factory flat 4 wiring and plug under the bumper. There is a fifth, blue wire labeled "electric brake" that is taped to the harness and connected to nothing. The fuse and the relay are not in the fuse box, but that's not a problem. The standard square gray connector for the brake controller is under the dash just behind the OBD port. I converted my '93 F-150 and my '00 Expy with ease, but this 07 isn't like the others and none of the after-market kits have an '07 variant. Anyone coverted a flat 4 to 7-wire (to include electric brakes, 12v power, and back up lights)? I hate to break out the wire cutters and electrical tape so early in it's life...
