What is Needed to Install a 7-Way on a 2007 Ford Expedition with a Factory 4-Way Connector

Question:

Hi, I just purchased a 2007 Ford Expedition with the 4 pin trailer connector. I want to have a 7pin and a 4 pin connector which would mount in place of the 4 pin. I undersatnd that the reverse and aux power hook up wires are not there, but there is a connection in the fuse box, so i also need 2 wires plus jacket I think a 10Ga and a 14Ga should do it at 25 long?. Brake wire seems to be there. Can you recommend which parts to get? Thanks

For the reverse lights, you would just tap in right there close to the rear. 10 gauge wire would be fine to run up to the battery for your 12V power. 25 feet should do it.

That being said, before you start your installation, you may way to check the rear of the Expedition again. On 1997-2004 Ford full-size trucks and vans, the 4-Way equipped trucks did have the wiring run, you would just have to splice into it. Your 2007 Expedition could very well be wired the same, we just do not have as much information on them as the Expeditions are not as common as say an F-150.

We have an article on how this is done, so it may be worth looking through the article and checking your wiring at the rear of the Expedition with a circuit tester, like part # PTW2993.

IF you do end up needing to purchase wire, we have part # 10-1-1, 10 gauge sold by the foot, and part # 12-1-1, 12 gauge sold by the foot. We do not have any 14 gauge by the foot.
