Video Transcript for Review of Tow Ready Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118243

Today we're gonna take a look at the Ford replacement OEM tow package, seven way wiring harness. Now, this is a custom fit part. It is designed to fit the 1999 to 2001 Ford super duty trucks with the OEM four way flat wiring. Now, this kit will allow you to upgrade your four way on your vehicle to this seven way connector. Now once you do install the seven way connector, the four way that is on here will not be functional anymore. You can also use this if you have a factory seven way on your vehicle that might be damaged.

This part here will replace it.Now, it includes everything shown here on the table. It includes the seven way, the 24 inch long wiring harness, the fuses, and the relays that will make this all operational. The plug right here on the harness, this is what you'll need to plug into the vehicle's wiring harness plug on your vehicle. And that plug is usually underneath the rear, normally on the driver side frame rail behind the bumper and the plug should match this plug right here on the trailing wiring harness then. And then you just plug that in.

The other end, right here, this is what we plug into the back of your seven way. You just line it up, push it in there, and it would connect to that.Now, we do recommend to mount this with a mounting bracket. We do sell those separately on our website and they're usually listed on this product page as a related product. Now also, once the wiring harness and the seven way's all connected in the back, the last thing you need to do is just install these fuses and relays. So basically, on the Ford super duties, there's usually two boxes in your engine compartment.

There's a larger box which is the power distribution box and then there's a smaller box attached to it which is the trailer tow relay block. What you'll do is open the covers on both of them and then that way, you'll be able to access the connections where these fuses and these relays will go.So on the bigger box, what you'll do, that's the power distribution box . You'll look at your owner's manual and just find the location for the trailer tow electric brake and the trailer tow battery charge fuse locations. And then you'll take these two large 30 amp MAXI 00:02:05 fuses and insert them into those locations. Once you do that, then you just go to that smaller trailer tow relay block which is attached to the bigger box and you'll look in the owner's manual, find the location for the trailer tow backup lamp relay and the trailer tow battery charge relay locations.

And then you'll take these two relays right here, insert them into the locations, put your covers back on, and your system will be all ready to go, and you'll have a seven way at the back of your vehicle. But that should do it for the review on the Ford replacement OEM tow package seven way wiring harness.

I have a 1999 F250 4x4 and wanted to upgrade from 6 round to 7 round to match the car trailer I had just bought. I had almost given up on finding a plug and play up grade and was preparing myself to start cutting wires. I'm so thankful that I found this web sight. They have a very large selection including the one that I needed. On top of that the video of how to install was spot on. I would not have thought of having to add a fuse and upgrade another under the hood. They were very helpful, great turnaround time and great product. I will definitely buy from them again. 472372

I bought the 118243 replacement 7 way trailer connector for my 2000 Ford F250 7.3 Super Duty. Hooked it up in less than an hour. I also needed the adapter bracket 11840. Without this bracket, the 118243 connector would not mount correctly to my truck. It would not clear the bottom of my bumper in the original mounting position on the bumper. I also bought the Pollak 7 plus 4 way connector because I have multiple trailers with different connectors. This product is HM40975 and I highly recommend that it be purchased with the other two products. The guys at eTrailer really know their products and are so helpful. They know what exceptional customer service is all about. Also, I love all of their online videos and information on the website that allows you to make informed decisions. Their prices are very competitive too. With free shipping over $99, they can't be beat.. For those reasons, I will not buy trailer gear anywhere else. 138981

This was an exact replacement as this item was missing on the used 1999 F-350 I purchased. Instruction manual showed exactly where to find connector on frame, and how to install the provided fuses and test. I can't wait to hook up my boat trailer for a trip to the lake! 33234

I bought a plug from Gaudin Ford that supposedly was for my truck- 1999 F250 Super Duty and it did not work. I found this site and took a chance and ordered the plug for a 1999 F250 Super Duty and it works perfectly! Half the price of the dealer and they offered to exchange it if it did not work- Ford said no exchanges or returns on their electrical. Thanks for your help in finding the right plug! 77221

So I was led to this website while shopping online for the wiring harness that I needed. I mistakenly ordered the wrong part and immediately called etrailer with my error. I spoke with a gentleman named Laser who immediately corrected my mistake and actually shipped the correct harness while I was on the phone. Because it was actually less than other online sites even with shipping. Thanks guys 575434

Fits my 2000 F250 Superduty perfectly. I ordered this with the 7 and 4 pole trailer connector HM40975 since my boat trailer has the 4 pin. Too bad they don't sell the wire harness without the 7 pole if you go that route. Had to shim 3/4" for the bracket or the plug would be obstructed by the bumper. I'm very pleased with the result and service. 404065

I purchased the 90° 7-pole wiring harness for the bed of my F250 and the OEM replacement 7-pin harness for the rear bumper. I'm the 2nd owner and for a long time I left the plastic bed-liner in it. When I removed it recently I discovered there was a hole in the bedside from the previous owner. I use my truck to pull a fifth-wheel camper too, and the bumper wiring harness pretty much maxes out my trailer's pigtail. Both wiring harnesses were very easy to install, and I was even able to trim the spacer provided with the kit to fit the contour of the bed where the previous owner had drilled the hole. It looks like it came installed from the factory! 36224

Converted the dually Ford F350 to a flatbed and just needed the wiring to plug into the factory 4-flat connector on the pickup harness to the connector on the flatbed's installed 7-way/4-flat combination plug. Already had the fuses and relays from pulling gooseneck before, so it only took a couple of minutes to plug in the connectors and do a light check on the trailer. Everything worked perfectly. Thanks George! 220444

This purchase was for my 1999 Ford F250 XL SD. It has the factory trailer wiring installed but came with the 4 way flat connector. This harness is Super Easy to install and just replaces the factory 4 way directly. It gives me the full capability I need for a trailer connection including the AUX Battery Charge line and trailer brake connections. All I need now is the trailer brake controller and I'm 100%! Thanks etrailer! Great Kit!. 692246

Etrailer has it right! The best products along with the technical support at usually the best price. The ford 7 pin harness I purchased only took about a minute to install.

I upgraded the tow package wiring on a "new to me" 1999 F250 Superduty from the jerry-rigged mess the previous owner had gobbed together to one utilizing the truck's existing trailer tow package, both for the rear of the truck and inside the box for the gooseneck ball hitch. The wiring harness, receptacles, et. al. from etrailer plugged right into the truck's wiring harness with ease, and I would highly recommend their products. Customer service was impeccable...assisted with an order mix-up on my part, helped me locate the truck's wiring harness plug under the dash, and provided help with finding the correct harness for an older model trailer brake that I already possessed. To the staff at etrailer---thanks and keep up the great work! When I need trailer parts again, you will be the first I contact! 629011

  • How to Install a Hayes Brake Controller on a 2000 Ford F-250
  • In order to install a Hayes brake controller like the Hayes Engage Trailer Brake Controller part # HA81760 on your 2000 Ford F-250 you will want to use the Custom Wiring Adapter part # HA81783-HBC which is a direct plug and play fit. I have attached a video which shows where the factory port is located for you. I took a look at you order and can confirm that the Ford Replacement OEM Tow Package Wiring Harness part # 118243 is correct for you.

  • What is the Correct Trailer Wiring for 2007 Ford E-350 Van?
  • There is a solution for you but Replacement Harness # 118243 is not a fit for your 2007 Ford E-350. If you have the factory tow package connections you will want the Reese Multi-Plug Wiring Harness for Factory Tow Package # 74682. This harness will give your van a 7-way RV-style and a 4-pole flat connector and plugs into the factory 7-way socket on your E-350. I've added a link to a video review of this part for you to take a look at.

  • How to Add Bumper and In-Bed 7-Way Connectors to 1999 Ford F-350 with Factory 4-Way
  • If your 1999 Ford F-350 Super Duty came with a factory 4-Way then all you need to add a 7-Way to your bumper and in the bed is the Tow Ready part # 118243 which plugs into the square/rectangular connector you're talking about and then a connector like the Bargman # 50-97-410. The Bargman just tees in to the US Car Connector on the Tow Ready part prior to connecting the Tow Ready 7-Way. I have attached sample installation videos that you can check out as well.

  • Wiring Diagram that the Ford Replacement OEM Tow Package Wiring Harness # 118243 Uses
  • If you check out the picture I attached the middle set of 7-ways is the wiring diagram/colors you'll need to use for the Ford Replacement OEM Tow Package Wiring Harness # 118243 that you referenced. The harness is already wired up correctly though so there wouldn't need to be any additional wiring.

  • Adding a Functioning 7-Way Trailer Connector to a 1999 Ford F-350 with or without Factory Connector
  • It sounds like your 1999 Ford F-350 either came with a factory 4-Way or no trailer connector at all. A dealership might be able to tell you what equipment the truck had based on the VIN so that is one thing you can try. Even if it came with a factory 4-Way you can still install a 7-Way with relative ease. First, follow those 4 wires you mentioned forward under the truck. If they plug into another square/rectangular connector then you can use 7-Way # 118243 which comes with the fuses...

  • Recommended 7-Way Wiring for 1999 Ford F-350 Diesel Without Any Trailer Wiring Harness
  • The Ford Replacement OEM Tow Package Wiring Harness, 7-Way (Super Duty) # 118243 is for vehicles that had a factory 4-way connector, so the harness was present near the spare tire. Since you have no harness, you will need to first add the hardwired 4-way # 18252 which is easy to install. This will give you the 4-way flat trailer connector and then you will use # ETBC7 to add the 7-way connecting the other functions. This kit will utilize your new 4-way flat and then give you the wire,...

  • Replacement 7-Way Trailer Connector for a 1997 Ford F-250 Light Duty
  • If you have a light duty 1997 Ford F-250 then you can use # 118242. This harness will not work on Super Duty models. For a Super Duty you would use # 118243. I have included links to the installation details for both harnesses for you to view.

  • Adding a 4- and 7-Way Trailer Connector to a 2001 Ford F-250 with Factory Tow Package
  • Yes! The wiring harness part of # 118243 will plug into the back of 7- and 4-Way connector # HM40975 on your 2001 Ford F-250. Both connectors have the same receptacle in the back so they are compatible with that harness in 118243. I have linked a couple of videos for these parts for you.

  • No 12 Volt Power on 7-Way Trailer Connector on a 2010 Ford F-350
  • Relays are difficult to check. Really the only way to do it is to get a relay you know works and try it. If that does not work it is possible that there is another fuse or relay associated with the 12 volt circuit. Using the owners manual and/or legend on fuse box lid you can determine if there is another to check. If your truck only came with a 4-Way wiring harness initially then the wire for 12 volt power is probably not run back to the connector. Trace the cord back from the trailer...

  • Replacement 7-Way and 4-Way Recommendation for 1999 Ford F-250
  • For a 7-way harness that will plug into the square trailer wiring connector of your 1999 Ford F-250. You would want the part # 118243 which is a confirmed fit. I attached an install video for you to check out as well. If you wanted to swap out the 7-way with one that includes a 4-way as well you could use the part # HM40950 to get both.

  • Correct Trailer Wiring Harness for 2002 Ford F250 or F350
  • The # 118243 harness you referrred to is compatible with 1999-2001 F250 and F350 models, and is not compatible with a 2002 model, which would explain why it's not working. Part # 74682 is shown as being the proper 7-way for a 2002 Ford F250 or F350. The 74682 would plug into the existing US Car connector under the vehicle, typically located on the driver's side frame rail.

  • Replacement 7-Way Trailer Connector for 2001 Ford F250
  • Since you're needing everything from the rectangular connector back, we have exactly what you're looking for. You'll need the Tow Ready # 118243. Once you unplug the existing gray plug, this connector assembly will take its place. I've also linked you to an install video. You'd then use an adapter like # PK12716 if you needed to tow a trailer that had a 4 pole trailer connector.

  • Replacement 4 and 7-Way Trailer Connector for a 2000 Ford F-350
  • You can use the Hopkins 4/7-Way connector # HM48470. All you will need to do is attach the wires from the old connector in the same places on the back of this connector then mount it where you want it. No other wiring harnesses are needed. The replacement 7-Ways we have for a 2000 Ford F-350 that also have the rectangular plug do not have a built-in 4-Way. We have # C55243 and # 118243.

  • Ford OEM Connector With Bare Trailer Wiring For 2001 F-350 Dually For Custom Install
  • For your 2001 Ford F-350 Dually, we don't have a bare wire kit with the gray OEM harness. I recommend using the 7-way # 20031 that is confirmed to fit and cutting the CAR adapter off the other end. This will give you the relays and fuses you need to make those wires function correctly as well. For a shorter length you can use # 118243. If you just need a 7 way connector, you can use # PK12-707E and connect the wires. If you need a wiring extension you can use # PK11-934. If you...

  • Replacement 7-Way Trailer Connector for a 2002 Ford F-250 Super Duty
  • I can only confirm 7-Way trailer connector # 118243 as a fit for up to 2001 Ford Super Duty trucks. For a 2002 what you can do is use harness # 40167 which is designed as in-bed wiring for a 5th wheel or gooseneck trailer but would work just as well to add a 7-Way at the back of your truck.

  • How to Activate Reverse Light Circuit of 7-Way on Ford F-350
  • We are unaware of any relays needed to activate the reverse light circuit of your Ford truck 7-Way. What you would want to do is run a wire from the reverse light circuit of your truck to the center pin of the # TR118665 and then one side of the solenoid run 10 gauge wire like part # 10-1-1 to the center pin of the 7-way and on the other side go to the truck battery. This will give you a higher rated circuit for powering the spot lights on your trailer.

  • Troubleshooting Brake Controller Blowing Fuses in 1999 Ford F350
  • There's many things that could be causing the problem your issue. When did the problem begin? If it started occurring immediately after the brake controller was installed, I'd recommend reviewing the installation process. Was the controller hardwired into the vehicle, or was a wiring adapter like part # 3035-P used? If the controller was hardwired, check your connection at the brake stoplight switch. Make sure the connection is secure, and hasn't shorted out. Make sure the circuit...

  • In order to install a 4- and 7-Way on your 2004 Ford F-350 you will first need to install # C55265. This will plug right into the port in the picture you sent.

  • Replacement 7-Way Trailer Connector for 2001 Ford Excursion
  • I'm not entirely sure what you're needing. The # 74682 is listed as a fit for your Excursion. It is designed to plug into the round US car connector that plugs into the back of the OEM 7-way. Further back on the wiring harness is a rectangular connector that resembles that shown on the # 118243. We don't offer that portion of the harness, if that's what you're needing, you'd probably need to obtain that from your Ford dealer. Another option would be the # HM40975-11998. You could...
