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.

The installation of this item on my truck took a total 30 minutes. It was so easy that I could not believe the project was done. The package is so complete and that allowed me to place it right where I needed it to be in the truck box. Thank you for the service.

Reason for this site used is because it fit well there was convenient and was out of the way. Also most factory installs are in that location for fifth wheels.

I needed to relocate the location of my 5 wheel plug-in. Because of a disability it is difficult to move around, the Endurance 5 wheel 7-pole plug was extremely simple to install. The factory plug- in made a simple connection. If anyone needs to install or replace 7- pole plug, etrailer has wonderful products. They make it possible to do it yourself and will be as good as if a professional had done it. There website if very helpful in choosing the right product for your needs and the videos are very helpful for the installation of there products.

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.

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.

I purchased this harness to fix up a rat's nest of wiring the previous owner did on the vehicle when trying to install a brake controller. This product was exactly how it is described and fit perfectly. It plugged right into the stock harness on my 99 F250 SD and required no splicing of wires at all. Very clean just like OEM. It was well worth the money to have lights that I know will always be working for me!

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.

The pig tail plug in allows me to now plug my goose neck horse trail into the bed of the truck. Prior to this I was using the plug on the bumper hitch which was not the best set up. Now no matter how tight of a turn I make, no problem at all with the wiring.

This looked like the product I needed to put a 7 pin connector in the bed of my F350 to plug in my camper, but I wasn't sure so I called customer service. The customer service rep was very knowledgable about my different options and assured me this would work great. It was easy to install and is far more professional than splicing in to wires. It took less than 1 hour to install.

I needed to rewire the " speghetti " wiring mess that trailer companies installed on my truck. What a mess but Doing business with etrailer was a wonderful experience. I ordered a a 5th wheel trailer wire kit to plug into OEM connector and a bumber 7 pin connector kit for my F250. All was Plug and Play. Took less than and hour and all lights, brakes, aux. everything worked perfect and first time. I now have a very clean, professional wiring. Looks better than factory installed.
Also all the LED lights I ordered for the boat trailer fit perfect and looks great. Very satisfied customer. Trailer Wheel and Frame is 10 miles away but I will be getting my trailer parts from etrailer from now on. Great Service and follow through on the order. I was notified and in the loop every step on the order and delivery process.
Thanks again

I originally order'd the same product from another vendor. It did not have the correct plug for a 1999 Ford F-350, so I returned it. The product from E trailer fit the ford harness as advertised. It had plenty of wire length to place the plug anywhere desired.
by: Jeff L08/07/2020
Product worked great! Now have the same connector in the bed of the truck and at the bumper. Easy installation with the factory connection.

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.
by: John J.03/20/2017
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.

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.

view full answer... - Second 7-Way Recommendation for a 2000 Ford F-350For a second 7-way you would the part # HM40157. This uses the square connectors like the # 118243 which is what you would have on your 2000 Ford F-350. This will plug inline with your current 7-way harness to provide you with an additional 7-way for you to install at the rear of your truck.

Troubleshooting trailer lights can be frustrating and it sounds like you've already put in a lot of effort. If the connector sending the signals on the truck side has all of the functions active and operating properly then you can simply replace the factory 7-Way connector on your 2000 Ford F-350 Super Duty with either the Tow Ready # 118243.

If it's plugged into a rectangular connector, you can use part # 118243 for a plug and play installation. The connector will be behind the rear bumper near the driver's side frame rail. Unplug the connector for the 4-pole and plug in the # 118243. Be careful not to damage the tabs on the connector. If it's a round connector, you can use the # 37185 adapter. Plug the existing 4-pole into the...

view full answer... - Recommended 5th Wheel to Gooseneck Wiring Adapter on 1999 Ford F-250 & 350 Super Duty w/Factory PlugGood news, I can help. Your year and model of Ford truck was made with two styles of connectors when they were being wired in at the factory. This means you will need to look at your factory 7-way under you vehicle and see if the back of the 7-way connector has the round adapter or if it has a molded cable that leads back to a rectangular connector on the drivers frame rail. I've attached an image of the two for you to better see. If you have the factory round connector on the back...

- Trailer Wiring For My 1999 Ford F-350 Super Duty With OEM Factory Tow Package And My 5th WheelThe first thing you will need is the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector, part # C55243. This will plug directly into your OEM tow package port. Once that is in place you will need the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation - 12 Gauge Wires, part # ETBC7L, this is what will add the 4-way and 7-way connection to your 1999 Ford F-350 Super Duty.

The reason for this is that they do not offer a plug and play in-bed wiring harness for a 1996 Ford F-350 like the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness part # HM40157 that you were looking at which fits the newer F-350's.

You will not need to remove one to connect the other. They can be connected at the same time. I do recommend using dielectric grease # 11755 to ensure you have the best possible connection.

The harness would plug inline at the connection between the factory 7-way and the tow package harness, or if the truck doesn't have a 7-way, the male portion of the connector will plug into the female tow package harness. You'd then want to use electrical tape to cover the un-used portion of the connector to protect...
view full answer... - 5th Wheel & Gooseneck Wiring Harness for 1999 Ford F-250 With Rectangular ConnectorWe do have the correct 5th wheel & gooseneck wiring harness for your 1999 Ford F-250 with the factory 7-way and rectangular plug, though it is not the Curt # C56070 harness you mentioned, as that is for the round plugs. For your F-250 with the rectangular connector, the correct 5th wheel & gooseneck wiring harness is the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug # HM40157.
view full answer... - Installing Hopkins # HM40157 5th Wheel/Gooseneck Truck Bed Trailer Connector in 2000 Ford F350To install the # HM40157 in your truck bed, you'd drill the hole at the desired location in the truck bed. Run the wiring carefully through the hole, and plug the round connector into the back of the 7-way that's installing in the truck bed. Next, locate the rectangular connector above the spare tire where the bumper mounted 7-way plugs in and unplug it. The wiring harness from the bed mounted 7-way would plug INLINE with the two rectangular connectors you've just unplugged.

For the frame bracket/ bed rail kit, use part # C16443-204. If you already have Curt bed rails, you can certainly use the # C16443 by itself, but we don't recommend using frame brackets and bed rails from different manufacturers. They WILL fit, but since they haven't been tested together, using brackets from one manufacturer and rails from another could yield an unknown weight capacity, which would...

If a 7-Way was added later an the truck did not come with one originally, you will need to use a different type of harness, # 20027.

There are actually two possibilities, because that model year Ford came with both a round and square connector leading to the 7-way, so you'll need to check under your truck to see which shape the connector on your F-250 is in order to get the right harness.
