In order to obtain the trailer wiring harness that connects the square plug under the vehicle to the back of the 7-way trailer trailer connector you can use the Ford Replacement OEM Tow Package Wiring Harness part # 118243. I understand that you are just looking for the wiring harness portion but we do not offer this separately as this is more or less a part of the factory wiring which we don't really carry therefore this is your best option unless you want to go to the dealer. The harness can be removed from the above plug.

The Ford Replacement OEM Tow Package Wiring Harness, #118243, will not fit the 2002 Ford F-350. For the 2002 Ford F-350 Super Duty, it is a hardwire situation. If the truck came with a 4-Way flat trailer connector, you will need to add part #37185.…

For your 2002 Ford F-250 we have the Hopkins 7-Way Fifth Wheel Harness part #40167 which is very similar to the #118243 except designed to fit your specific vehicle. As long as you have the factory 7-way harness at the rear of your truck this is…

The grey connectors on the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness #40167 plug in line of the factory 7-Way #118243 on the 2002-2004 Ford F-250 & F-350. This connector will be behind your rear bumper.

Answer 5

The plug on the end of the Tekonsha #118243 that connects to the vehicle does indeed have 4 larger pins and 4 smaller pins. I included a picture of the plug end of the harness, but it isn't super easy to see the pins. It should be noted that this…

Answer 6

Although the #118243 shares the same rectangular plug located on the driver's side frame rail as later models, Tow Ready only confirms it as a fit for 1999-2001 Super Duty trucks while the #118242 fits the 1997-2003 F150 and the 2004 F150…

Answer 7

Take a look at the back side of your existing 7-way trailer connector. There should be a round plug connected to the back of the actual trailer connector. You should be able to slide out the gray catch on that connector then remove it. That round…

The Hopkins harness part #HM40975 has been confirmed as a fit for your 2002 Ford Super Duty that had a factory 7-way and will provide you with both a 4-way and a 7-way. I attached an install video for you to check out as well.

Answer 9

There are replacements for the factory 7-way on your 2002 Ford Excursion but part #118243 will not fit. Instead I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package #74682 which will plug directly into the 7-way socket of your…

Answer 10

The #118243 connector you referenced isn't a confirmed fit for the 2002 Ford Super Duty. My contact at Tekonsha tells me that the connector used on the #118243 is identical to what's on your truck, but it might be pinned out differently. Over…

Answer 11

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…

Answer 12

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…
