Expedition tow charge wiring

[TomH]

My 07 Expedition has the towing package with a 4 pin connector. I had it converted to a 7 pin round however they forgot to connect the tow charge wire. Is it in the same harness as the brake controller wire? What color wire?
Thanks TomH

What do you mean by tow charge wiring? Never heard of this term.

Its the wire to charge the battery on a trrailer while towing it.

Tom,

Found this on another post. Pretty self explanatory, also, check in your well where the jack is, (in the back on the rh side), their should be a bag with fuses and what not to help make this connection.

Thought I post the solution to my original problem; maybe it will help another Fordster. My 2007 Expy came with a 4-pin flat trailer connector. To upgrade to a 7-pin connecter and add a 5th wire to charge my Jayco pop-up trailer battery, I added a trailer battery charge relay (#56) and a 30A trailer charge fuse (#13) to the main fuse/relay box under the hood. Next, I found the orange wire that comes out of main fuse/relay box; It is going to a large connector near the master break cylinder. Use a tester to ensure you have the right Orange wire before connecting to it (it's right on top of the bundle of wires, next to a yellow wire). Then I ran a 20 foot length of #10 AWG stranded wire, with a protective sleeve over it, all the way to the new 7-pin tow connector. Now my trailer battery is charged with the protection of the fuse and relay that is part of the optional tow package from Ford.
