I have an 08 Expo EL EB. My Dad has an 08 Expo EL Limited. His came with a trailer wiring hookup with both the Class I (4 Pin) and the Class IV (7 Pin). Mine came only with the 4 pin. We have a large 24' trailer with elec trailer brakes. His has the brake control mounted in it and the trailer brakes work great when plugged into the 7 pin. We intalled the brake control as Ford put a plug for it under the dash. I have the same plug under the dash. If I get a brake controller will the trailer brakes work with my 4 pin connector at the rear of the truck? If not what do I need to do? I didnt find much help in the manual. Thanks in advance.

 

4 Pin is for lights only.

You would have to install either a 6 pin or 7 pin connector. I don't know about down there, but 6 pins connectors are becoming really uncommon around here.

 

Your local RV parts store will have a 7 pin connector cable that will plug into your wiring harness.

 

Ok. Thank you. I saw under the rear bumber a wire labeled elec brake control but it does not go to anything. Thanks for the input.
