Replacing 7-Way Connector on 2004 Ford F-250 with a 4- and 7-Way


I have a 2004 f250 6 liter diesel. The wiring harness now has a set up for a gooseneck and it has a 7 way on the hitch which has no 4way and a lot of corrosion. I would like to upgrade the whole thing but the factory plug seems way too short for this set up? Is there a set up for all three plugs or at least the 7 and 4 way plugs?


Expert Reply:

On the back of the factory 7-Way connector on your 2004 Ford F-250 there is a round connector that plugs into the back of the connector. If you unplug that harness it would plug into the back of # HM40975. You could also tee in an-in-bed 7-Way using # C56070 which would plug in between the factory harness and connector # HM40975.

If want a little more length between the factory harness and the connector you can use # C55774. There isn't a single harness that has all 3 connectors. I have included some links to videos on these parts for you.
