Quickly and easily install a 4-way trailer connector on your Ram 3500 with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.
Features:
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind your rear bumper.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.Fit perfectly the whole hitch and wiring install was a breeze.
Hitch is on! Piece of cake to install, everything lined up perfectly. I ordered wiring for my car according to my cars build sheet stating that it was pre wired for a tow package but I'm unable to locate any type of plug in so I'll need to return the one I ordered and get the other type. Please advise me the best way to do that.
Just what I needed..came in early than planned and fit right..thanks
Worked as it should. Only used with a small trailer. Good product as always with etrailer. If not good, they make it right.

This was my first time pulling my 20 foot CC boat and brand new trailer with my 07 Trailblazer which came with the factory installed tow package including the factory installed 7 pin connector for the lights. I ordered the wiring connector item as it had a guaranteed fit for my truck. I went to install it and initially thought it did not fit correctly as I was trying to attach it by flipping up the pin connector cover underneath the rear of my truck and putting it in there, this was wrong but I did not know it....briefly went and reviewed my truck manual but it did not go into any detail on how to connect the trailer wiring, went online and finally found out that I needed to reach behind the cover piece and squeeze in 2 tabs to release the tow truck wiring connector, this is what the Hopkins harness is designed to fit into and it worked perfectly. As I just did this I have no idea what the longevity of the wiring harness will be but it does come with a nifty little cover to protect the electrical pins. As I do not plan on using it that often I removed the harness to keep it safe and sound.
Perfect fit for my 2005 GMC Sierra! The 6 narrow pin male plug fit perfect into my 7 narrow pin receptacle on my truck. It gave me parking lights, brake and my individual turn signal lights all from the four pin trailer plug. Beware of internet re-sellers that say their #41155 will work if they are showing you 6 wide male pins that will not work. etrailer is the best! Super fast shipping, fantastic customer service and all at a great price! Thank you!

I could not be happier! A year later through a sloppy winter and my Hopkins Trailer Light harness has been flawless. Keep up the great work!
Customer Service Reps kept me informed about the status of my order. The delay was because the manufacturer was slow in shipping to etrailer.com. Once received, I was immediately notified that the item was on the way. I can always find what I need at etrailer.com, the price is great, and the service is superb. Thanks guys for always being there to help me with my needs. Keep up the GOOD work!
Items worked as expected, needed some assistance with harness but satisfied overall
product functioned as expected...... the round plug that fit the tow vehicle needed some slight modification.... after i year the grounding pin on the flat four plug fell out,.... simple enough fix....... still works great.

Thank you for leaving a review! The product page does say all you have to do is plug it in if you want a 4-pole connector. Which is true, you can just tuck those red and blue wires away unless you need the braking and an auxiliary power wire. It sounds like your trailer just has a 4-pole flat for trailer lights so you do not really need those 2 extra wires if that is the case.
The trailer wire harness for my 2014 Dodge Durango worked perfectly. It fitted into the prewired factory wire harness attached behind the bumper. I had to have the dealer program the vehicle for the lights to work. The dealer did not charge me for this service, since I was having some other work done on the vehicle they did it as a courtesy. Normally it cost about $50 to do the programming.
4 stars is for quick delivery and easy ordering, I have not used the extension yet. But, thanks for everything that went so well so far.

I have used this many times. Very easy plug and play install and works well.
Ordered the Hopkins plug-in simple wiring kit with 4 pole connector (41155) for my 05 Nissan Titan. Received what I order very quick. Connected perfectly to my truck with out any issues. I was ready to attach my trailer and go fishing. It was exactly what I ordered.
I have bought three different trailer hitches, wiring and other items.
Everything fit perfectly, the videos are excellent and the staff is knowledgeable,and patient with us do it ourselve customers.
Pricing is fair, so they deserve 5 Star rating.
The reason for three stars is that you'll need a relay tow package kit in order for it to work . It should come with the 4 flat plug for the trailer lights to work . Other that that simple plug & play done
Quick delivery and easy install. Didn't work and found out that if the towing package didn't come on the Grand Cherokee, you have to go to the dealership and have it programmed or "turned on" in order for it to work. No fault of etailer.
Plug in and works great. Took off the old plug that was all green with crud. Fit my truck just as ordered. All trailer lights work as suppose to.
Simply did what it was supposed to do. Unplugged the old wiring harness and replaced it with this new one.
Quick delivery and product seems good. Connection to my Audi is not perfect, there is no snap lock on connection. Taped it together with electrical tape.
Harness was perfect length and all connectors were correct. Only difficulty was having big hands to access vehicle tow pkg plug.
THE HITCH FITMENT WAS PERFECT. THE WIRING HARNESS WENT TOGETHER EASILY. GREAT PRODUCTS, PACKAGED AND SHIPPED FAST.
I MAY PURCHASE ONE FOR MY VAN.
THANKS.

I purchased a plug-in wiring adapter for my 2017 GMC Sierra. Great price, product arrived at my house quickly. Works fine, fits great, no problems. I'd recommend this company and product to anyone out there.

I store the device inside my truck and do not leave it attached to save it from the elements, so far one year later works perfect.
