Trailer Wiring Harness Installation - 2004 Ford F-150

Video Transcript for Trailer Wiring Harness Installation - 2004 Ford F-150

All right. Today on this 2004 Ford F150 were going to install part number 118247. First thing we need to do is go ahead and unload our spare tire and get it out of our way. This way we have access to the wiring connection we need. Now, the wiring connection were looking for is going to be on the drivers side frame rail pointed out here, and well go ahead and disconnect it. Well push down on the tab and pull it apart.

Next, we need to remove the ground screw. Well go ahead and remove it. Now we can go ahead and start installing the new part. Now the wire harness is shaped like a T so well take both halves of the T and install them into the wire harness; one on each side. Well push them together until they click.

All right, now well take our white wire at the ring terminal and add that to the original wire with the ring terminal and bolt those two back together to the frame using the ground screw. Now we need to install a seven pole connector. Now, this kit does not come with any brackets to hold the seven pole in place. So, were going to add a couple of part numbers. Were going to use part number pk12711u to hold our seven pole bracket.

Were going to use part number 18136 to mount the whole assembly to the hitch. Well start off by putting the two brackets together. Now, were going to intentionally take one bracket and install it in reverse fashion that way we keep the seven pole connector as close to the hitch as possible. Well bolt these two together and then well take that assembly and well go ahead and clamp it to the hitch. Well take the band clamp, run it around the hitch and through the bracket and then tighten it down.

Well make sure its level first and then well tighten it down for good. Now well go ahead and take our wire harness and run it through the bracket. Well remove the little gray lock thats on top then install the seven pole connector. It also just snaps together. And, then well reinstall the lock. And, then our seven pole connector will get bolted to the seven pole bracket. All right. Were done with the back of the vehicle. Now we need to add a relay to the front. Well go to the passenger side front seat and there will be a kick panel down below that we have to remove to get access to the fuse panel. Well remove the door and then remove the lid to the panel. Then well go ahead and add our relay that comes with the kit. This will power our 12 volt power supply with our hot lead going out back at the seven pole connector. Now, you want to check your owners manual for proper location of this circuit, and then reinstall the covers. That will finish it for our install of part number 118247 on our 2004 Ford F150.

7 way tow harness 118247 What a great experience dealing with Etrailer on this purchase. The actual transaction went smoothly and follow up communication from Etrailer staff was exceptional. I was immediately informed of receipt of my order, when my package was shipped, and receive a follow up message within hours of it's delivery. Their staff deserves a A+ for this transaction and I'll be back when and if I need something else. 3920

I looked and asked around everywhere for a seven pin plug. People wanted to charge me a couple hundred bucks to install it. I saw this video on youtube and went to the website and ordered it on the spot. Easy to install. Took five minutes. I wish it would have came with mounting bracket, but other than that, AWESOME!!!!! Definitely recomend this sight! 118598

I installed the items I orderd on a 2004 Ford F150 without factory trailer package. The items etrailer.com suggested to buy fit perfect and work perfect. They were easy to install considering the truck is 8 years old. Some rust to deal with. I would give etrailer.com two thumbs up. 80791

I am very pleased with the wiring kit I had purchased from your company. The instruction were complete and the shipping couldn't have been quicker. The plug in harness fit my truck and was very easy to install. I have only one suggestion, and it is a minor one at that. The kit does not contain a mounting bracket for the vehicle plug itself, so a little time was spent fabricating one to mount the plug. Again this is a minor suggestion and will not keep me from visiting your website and/or making any purchases in the future. Thanks for a great product !!! Tony 142644

Plug the existing 4-way into the adapter and attach the blue, black, and purple wires to the wires going into the connector on the driver's side frame rail.

If your truck only had the 4-pole trailer connector instead, you could then use the # 118247 to install a functioning 7-way. The connector under the dash is located above and a bit to the right of the OBD port, just above where the driver's right knee would be.
