The trailer plug went bad on my 92 F150 several years ago. This plug is the same as my 10 F350. I like the combination 7 spade/4 pin. Other combos have a rubber flap to cover the 4 pin plug. I doubt I’m that disciplined and I would think that rubber cover would dry rot and break off. This plug has spring closure doors and looks great!

The service provided by George and Lacey was the best part of this transaction. Lacey helped me find the right parts and sent me a video about installation. They both worked to correct my order and customized the delivery date. The parts were precisely what I needed to get power to the bumper for a small trailer and bike rack. A few comments: order more butt connectors as the mfr sent 6 and there were seven wires on my Colorado. When connecting the tail harness to the truck harness, be sure all the wires on each side are the same length. The yellow wire strippers take some getting used to, so practice on several wires first. I’m an ‘average’ handy person so these last two suggestions didn’t come naturally to me, but overall this was a pretty simple installation. When I tested it and all the lights worked, I was a happy camper.

I have a 2017 SantaFe I have 2 different trailers and need both types of plugs I am using this product along with a curt class III hitch and a curt 56332 wiring harness.

This is a fantastic quality part and an excellent alternative to Ford's OE connector (the difference being this one is far less expensive and does not have the Ford emblem. I used the connector to replace the 7-Pin/4-Pin combination plug on my 2002 Ford Super Duty after swapping the bed/bumper/tailgate from a 2012 Super Duty. It is a vastly superior connector in that the 4-Pin is integrally wired with the 7-Pin as opposed to having the 4-Pin spliced into the harness. I would definitely recommend this part for any towing rig. I eve put one on my father's 1995 Dodge Ram 2500. Don't hesitate to order this one!



- HM40975-11998

Fit exactly as required and works properly. U-tube instructions were easy to follow and installing went smoothly except for the one butt connector that I could not get the wire to stay in.



- HM40975-11998
by:

I’m glad I chose this over a single plug! No matter what you have on the hitch, you’ll have the plug for it. The pigtail is plenty long enough and the bracket makes for a simple installation. Get some shrink tube or shrink wrap butt connectors as the ones included aren’t going to keep weather out for long.

This is a great affordable option to replace your worn out or damaged OEM trailer recepticle. The fit is perfect. It is made by Pollak which is the same as the Ford one you replace. I damaged mine and took the pin connectors out of new housing and installed it on my F350 without splicing wires. Worked perfectly.

Great product! Fits the factory hole in the bumper perfectly. Attaching the wires was a pain but that was due to GM saving $1 by just cutting the wire ends and not installing a plug......but they were all there so that was a plus. If you do install this setup AND you install a hitch, leave the spare tire down while you attach the wires. There's plenty of wire with the plug but the factory wires are up kinda close to the underside of the bed so not a lotta room. ALSO spend the extra couple dollars and get the heat shrink butt connectors, they're available here in whatever size you need. Another thing to think about, if you plan on eventually installing bed/ cargo lights any time soon, now is the time to add that extra power wire before you crimp, shrink, and tape the hot wire......

Bought this trailer connector to use instead of the flat 4 wire connector. Wanted a nice finished look on the rear of the vehicle without any hanging wires. Mounts to the Draw Tite mounting bracket without any modification. Only minor problem I had was with the wiring. The wire colors are not the same between the 4 and 7 pole connector. A call to etrailer got the problem resolved. Great customer service!

This is the same look as a factory install. I was greatly pleased with the overall installation. Super easy to wire up and looks great in the bumper. My truck has the clean factory look for way less than what they had quoted for an install.

Only gripe, the plug wiring on the back is at a 45° and the plug in on the front is at a 90°, so dont wire up the wires by the wiring plug but how the plug in on the front would plug in, I made the mistake, but other than that, works great, looks great, fixes botched wiring like my truck had with just twisted together and taped up wires, easy install

Good product. A dust cover for the back of the plug in socket would have made the product excellent. The open area on the plug will catch water and dirt. Color coding of wiring was off, usage of my volt ohm meter confirmed all the wiring connections. Liked the wiring information molded into plastic covers.


Comments
When the wiring harness is plugged into the back of the trailer connector socket, there should not be an open space to allow dirt and water to get in. To make sure this connection stays free of dirt and grime, dielectric grease # 11755
Dielectric Grease for Electrical Connectors, 2 oz.
$12.94
can be used at the connection. It is always a great idea to test wires for function before making connections. I have linked a photo of these wires connected showing that the wire colors do not match the factory wire colors. It would be very rare that the colors did match by function.

From start to finish, this has been a great experience! I wrote a detailed email explaining my situation. Within 24 hours, I received a response with a link to the exact product I needed. Product was priced well with good shipping rates. Order was shipped out 2 days later and I received an email that it would get to my house on Tuesday, but the part showed up 3 days early!! It's almost like Christmas!! I haven't yet had time to install the product, because I literally received it just one hour ago, but it's easy to tell that this is a super quality product. I was actually expecting a flimsy bracket that might have to be reinforced...not required. Very heavy duty bracket with self-tapping screws included along with wire connectors and of course the connector itself. I am very happy with my purchase and if will follow up with pictures and more if I can.

Excellent! Simple install for most anyone with a basic understanding of wiring. Connector works as great today as when I first installed it shortly after posting my initial comments.

  • Trailer Wiring Harness for 2007 Nissan Frontier XE Without Factory Tow Package
    For your 2007 Nissan Pathfinder without factory tow package you will need a kit that includes the relays to activate the trailer wiring.

  • Replacement 7-Way Recommendation for a 1997 Jeep Cherokee
    Since your 7-way does not have a round connector that would allow it to easily disconnect from your wiring harness you would want to go with a replacement 7-way that has a lead of wires like the part # HM40975-11998 so that you can wire your vehicle's wiring to the 7-way.

  • 7-Way Wiring Harness for 2013 Ram 1500
    Yes, the Pollak 7-Pole and 4-Pole Trailer Connector # HM40975-11998 could be hardwired to your 2013 Ram 1500 but we do offer no-splicing direct plug-in 7-way 5th wheel harness kits like # PK11893-11932 that fits the Ram with factory 7-way. We also offer just a 7-way/4-pole socket, part # HM40975 that connects to a round U.S. Car connector. If your truck has neither a factory 7-way nor a 4-pole you can instead use 4-pole kit # 119179KIT and then add our # ETBC7 7-way kit. Together these...

  • What are the Wire Functions on a 7-Way Trailer Connector on a 1991 Ford Bronco
    Its possible that the trailer connector on your 1991 Ford Bronco was added aftermarket and not all the functions were needed so one was not installed.
