Question:

I have a 2005 F250 and I am needing a new set up for my truck to hook up the trailer lights. The only one I have seen in your catalog is #118243 which is for the 1999-2001. Do you have the product for a 2005. Thank you

Expert Reply:

For your 2005 Ford F-250, I recommend the 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End # HM40975 if you have a factory 7-way or factory 4-way. If you prefer the look of the # 118243 which is not a confirmed fit, I recommend the Replacement Multi-Tow 7-Way & 4 Pole Trailer Connector # 74682.

If you truck does not have the factory 7-way wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56032. Then to get 7-way functions, you will need to add the Brake Controller Wiring Kit # ETBC7 to get the other functions and the 7-way connector. This connector will give you the trailer light functions even if you don't use the trailer brake function.

For a brake controller for trailer brakes, I recommend the Tekonsha Prodigy P3 # 90195 because of the ease of use with the easy to understand LCD screen and proportional braking. If you have the factory 7-way or factory 4-way, then you can easily connect it with a wiring harness # 3065-P. If you don't have the factory wiring, then the # ETBC7 will be the route to go.
