Question:

Hi I have a 1996 f350 with a factory flat 4 pin towing plug. Id like to add a round 7 pin and a brake controller. There are two unused factory round connectors under the rear bumper. There is also a factory female 6 pin plug under the dash by the stick shifter. What do I need to do to add the 7 pin round at the rear and a brake controller? Thanks, Brian

Expert Reply:

Since you already have a factory 4-way flat on your 1996 Ford F-350 you will need the Adapter 4-Pole to 7-Pole # 37185. This will plug into your factory 4-way and the rest of the wiring will have to be spliced into your factory wiring as I do not see anyone makes wiring for your factory connectors.

The Tekonsha Plug-In Wiring Adapter # 3035-P will allow you to plug into the 6 pin connector you found under the dash. Then you can connect the Tekonsha Prodigy P3 Trailer Brake Controller # 90195.

Thank you for the info. Since I am plugging the brake controller into the factory 6 pin under the dash do I still need to run the power wire from the truck battery to the 37185 at the rear bumper? Thank you, Brian

@Brian If you do not already have a power wire at the back of your truck then yes you will still need to run the power wire to the 7-way. This power wire charges the breakaway battery on the trailer so should your trailer become disconnected it would still stop the trailer.

@BudM Thank you for that info. Will the rest of the seven pin connector still function without the power wire ran? Is it just the breakaway battery that needs the power wire? Thanks again for your help, much appreciated.

@Brian Yes, everything else will still function properly. On most trailers the charge line is only for the breakaway battery. Some will use it for a coach battery like on a camper.
