This T-connector wiring harness uses your factory tow package to add a 7-way socket in your truck bed while also retaining the use of the 7-way at your vehicle's bumper. The harness plugs into the back of your 7-way at the bumper and also into your factory wiring. And it provides 10 feet of cord to run the second 7-way connector to your truck bed. Installing a second 7-way connector in your truck bed makes it easy to connect the 7-way plug from your fifth-wheel or gooseneck trailer.

Pretty much plug’n’play. Just drill the hole in the bed side and pull the wiring through. Works great. I’d buy it again. 583875

I installed this kit on our 2001 F350. The price was great and kit was easy to install. Once the hole was drilled it may have taken 30 minutes. The only draw back was the wiring was a little to long. 439324

Installed this in my 2001 F350 dually to replace the one that came in the truck because the accessory wire didn't work, and the wiring had been spliced in, and was a mess. The HM40157 went in easily. The plug-in connectors cleaned up the wiring nicely. 403353

The most important issue when ordering this type of kit is the picture that shows the type of connectors for the vehicle wiring harness. My '99 SuperDuty had the connectors in this kit instead of the ones in the manufacturer's compatibility matrix. Remember some truck manufacturers do not always use the same parts for the entire model year. Be familiar with your vehicle and look at the parts carefully. The kit was good quality and was very easy to install. Took less than 2 hours to install. Be sure that after you make the hole in your truck bed, clean up the sharp edges and paint the hole to prevent rust. enjoy this kit, it provides for a real professional installation. 356139

Harness is long...if you plan on installing it where etrailer.com recommends (between tailgate and rear wheel), you will have to coil it up or cut some out and re-splice. 356057

The wiring harness fit my 2000 F-350 as advertised. This was the only website i could find that clearly listed this harness as being a direct fit to my truck. 345545

I placed a phone order for this and they were very friendly,helpful and professional. The harness was delivered promptly. this is a very nice harness. I installed it into my f250 and it tested great(have not had a chance to hook up trailer). The harness is a good length and appears to be well constructed. I would definitely buy this product again for another truck and would highly recommend it. 325549

Great product, easy installation. If you want to get an in bed trailer plug and keep the bumper hitch plug operational this is a good way to go. Great service from etrailer.com fast shipping. If the opportunity comes up I will recommend to friend or family. 303394
