Adding a 7 pin factory wiring harness

[Texasliam]

I'm getting mine built without a towing package. Has anyone had the 7 pin factory wiring harness installed after delivery, so that it integrates with existing electronics. I'm trying to avoid an aftermarket break controller. Tell me the details please.

So Lumen just released a 7-pin tow harness kit 2-3 months ago, and it is sold via Ford Accessories. No personal experience with it, but I read the instructions and it seems to a near-factory-like replacement as it plugs into the same harnesses in the same locations that the factory tow module uses.

I ordered the Lumen kit last month. So far all Ford has sent me is a few emails telling me it's on backorder.

Going to give this a try, found it for half the price on ebay. https://www.curtmfg.com/part/51180

I have one of these, and have been using it for over year now. Luv it and it works like a champ!

This will not help #Texasliam at all. He is not getting tow so there will not be anything to plug that in to.!

Go to this thread and scroll down to post #23 where I laid it out for you. Even with tow package from the factory there is not a brake controller, only the 7 pin plug and receiver hitch. This Redarc brake controller is what you receive when you order from Ford accessories.

I ordered mine a week ago and it arrived 3 days ago .Working on the installation today.
I had the ford 4-pin harness on order but had waited a month and it was still back ordered. Saw this 4/7 pin from lumen was out so switched my order over. Guess I got lucky.

Install is done. It was a bit of a pain, but it is a nice clean install. The instructions leave a little to be desired, had to do a lot of head scratching.
The worst part was the wire harness doesn’t have the right terminals to fit the existing plug. I toyed with it for an hour and a half before remembering there splices and 4” wire pieces in the box. These do have the correct ends so you have to cut and splice the harness… this was not in the instructions.
Hooked it up the trailer and everything works. Odd part is that the instructions state you have to get into FDRS and activate the trailer setting. I did not do that and it works, not sure why, but I’m not complaining.

So, BroncRider, what did you do for the trailer brake controller? It doesn't show this in the kit from Ford? Did you buy a Redarc seperately and install it? If so where did you plug it in?

Thanks

I'm going to tackle this install over the weekend. As you said, the instructions are definitely lacking. Can you share anymore about the splicing you had to do? Any tips to help reduce the head scratching coming my way would be greatly appreciated!!

The Ford accessories website has 20% off orders of $300 or more (Summer20) if you select dealer install it’s puts it over that threshold. I’ve attached screenshots. Also remember if the dealer installs it then it’s covered by the warranty. Well worth not having to put up with the aggravation. I’m scheduling for next Friday.

I ordered the same thing!

I haven’t added a brake controller yet. Will probably go with Redarc when the time comes.
