I replaced my Toad with a 2012 F 150 Ford and took it to Camping World to have the wiring, tow bar, and Invisa Brake's installed to be towed behind my 2012 Winnebago Journey. Although, they probably did the job properly (brakes worked as did the turn lights) I was not happy with the job. The Breakaway switch was mounted so it protruded beyond the front bumper and the 4 wire plug on the Ford was unsightly and protruded as well when not connected. The invisabrake also has a separate wire that needs to be plugged in for towing, and it was strung to tight and unplugged it self when ever a tight turn was completed.
I decided to rehang the brake away switch and electric plug myself and since the brake wire was an extra step needed when hooking up, I would change the 7 wire harness that was reduced to a 4 wire plug in for the Ford to a seven on both ends and use one of the unused wires within the harness to replace it. The wire that is designed for use to power the backup lights and as additional items was not being used. I cut this from under the Journey and am now using it for the brakes. I now have a dilemma. I noticed the tail lights are not connected. The turn lights and brake lights are in use but there are no tail lights hooked up. Is this normal? If I do connect that wire so the toad would have tail lights, would they need another diode? I cannot remember that they were connected on my previous Toad.
