Most Popular Wiring Harness for 2003 Dodge Ram Pickup

The Roadmaster Tow Bar Wiring I purchased works great and was reasonably easy to install on my 2012 Dodge Ram 3500. It is a great product at a decent price and I would highly recommend it. Thanks guys.

I installed the kit today. It came as advertised. Good product and would buy it again.

The wiring system installed on my 2016 Ram was easy to install and continues to work perfectly

Went pretty easy. Holes for bulbs do fit in the rear lights. I had to use a 6way plug that had a 4way line on it also.

Very complete kit. My only problem mounting it in a 2014 Chevy Spark is the limited space for the diodes. After much trial and fitting I found a suitable location. See photo.

This item was recommended by Jameson once he saw what I was planning to order for the tow bars and brake system. It was installed by a shop on the etrailer authorized installers list, along with everything else for the entire towing system. It does attach to both vehicles just fine, although at first I wasn't sure it was fully attached on the motorhome side. I was afraid it would just slide back out, but it hasn't.

Got the kit installed. Using on my toad (RAM Dakota) to be pulled behind my motorhome. My first one like this and easy and good quality product. Highly recommend.

I will tell you what I like about this wiring converter. IT just plain WORKS exactly as it is supposed to. I used quality crimp connectors that seal with heat and the installation was easy and after more than a year and all kinds of weather there have been no issues. I am not surprised as I have bought from etrailer before and have never had a problem with an order or quality.

I had never wired a vehicle for flat tow before. So I called both Roadmaster and eTrailer several times about the issue of 7-pin RV to 6-pin towed vehicle. The confusing issue was that my Tiffin Allegro RED Class A motorhome has the yellow turn signal lights separate. But I learned through this process that the 7 pin is already set up NOT to need your Brit Lite Converter. So, it sits on a work bench in my barn, un-used. What was it? about $[XX]?

I needed to wire our ‘17 Chevrolet Sonic for towing behind our Motorhome. My local shop wanted over $xxx to install such wiring. Online I found the Blue Ox wiring kit and decided to do it myself. The kit and instructions were very complete and informative and it took me about three hours to complete the installation. The time consuming part was removing and reinstalling trim and panels to hide the wiring inside the car. The thing I like most about this kit is it’s independent of the cars wiring system and I’m very happy with it.

I put this base plate on with the assistance of my wife very easy to install. Do recommend the video to install

i used this on my trailer so that i was able to use taillights with separate (amber) turn signals, it works like it is supposed to, BUT it doesn't work with LED tails bc it drops the brake wire voltage coming out of the convertor to 10v causing the brake light LEDs to not function properly; i solved this issue with a voltage regulator (10-32v in - 13.8v out) so if you've got a little wiring knowledge or are using incandescent taillights then it will work great for you.

1 Tail Light Converter - C56196 : i was a little confused, but finely figured it out. 2 Tail Light Isolating Diodes (Qty 4) - 48955 : i was told i would need these (their for towing a vehicle, not a trailer) etrailer salesperson should had known that(they were told) wasted money, cost to ship back

Haven't installed yet but service was excellent

Must easier to install

Works great; replaced a cable that didn't have the coiled area this one has, which allows one to have all the cable length one needs when making turns but doesn't continually drag, which among other things shortens the life of the cable.

I have had this for a year now and have put it through quite a test. After it arrived I attached it and thought that the coil was wound a little tighter than it should have been, which made me concerned that it would pull out of the sockets. This is not a part of the towing package you want to have fail, so it was more than just a passing issue. Nonetheless, two cross-country trips and additional shorter trips and everything worked out perfectly. The connection stayed together, the cable did not drag or rub anywhere, and the lit ends that I thought were a gimmick proved to be really useful, convenient and reassuring, allowing me to check the connection by just looking at it. I would buy this again if I needed to, but I don’t think that will ever be necessary.

Just as described- the extension fit perfectly and worked.

I got this to replace the old, cracked wiring on my Snowbear utility trailer. Worked great and was the perfect long size. Made the job easy. Would buy again. Great quality.

This place is the best! Placed my order- easy peasy-delivered on time- Watched install video- again made it so easy and saved $1000 installation fee!!! Thanks for being a great company and special thanks to Carol C my order specialist !!!

I installed this myself along with a tow bar from another company at the same time, in about 4 hours. installation was straightforward and worked perfectly. saved about $800 in total labor.

Very handy to have

Used these to tow aluminum body F150. Magnets strong enough to securely attach below rear bumper which is about the only steel part available. Super easy to set up and they work perfectly

Great friendly service & superior knowledge of the product

This the second set for my second car. Very simple application

The tail light kit was easy to install, but I had to replace one of the lights within three months. The lights don't appear to be very durable. I purchased a different LED bulb as a replacement and it appears to be working good now.

Easiest install ever but I took away one star because the connector did not snap together at the tail light. Tried everything to get them to snap in like the stock connector but they would not lock in. Hap to tape them so they wouldn’t pull apart.

I bought a complete flat tow parts fir a jeep wrangler. I decided I could install myself. Your installation videos made it nearly a piece of cake. From a quote I got from a RV service business, I saved several thousand dollars installing myself. etrailer is the place to for your RV needs!

Took a bit to get to the rear lights on the wrx - trim pieces etc. But once there the instructions were easy to follow and the lights work great!

I returned this item in favor of the Curt Bronco flat tow light kit. The Curt kit is far superior to the Blue Ox kit. The Curt kit is totally plug and play no diodes to deal with. I would have bought the Curt kit from you if you sold it. You would be better served with the Curt kit.

Bought to install on vehicle to be flat towed behind motorhome. Installed temporarily on 2016 Ford Edge with LED tail lights by lying wires on ground. When connected to tow vehicle turn and brake lights are fine but running lights only lit side markers not actual rear lights that normally light when Edge controls them. Probably not legal. Must return. Photos show normal operation and kit operation.

Order was processed and shipped quickly. Install was a breeze thanks to website video.. Great experience.

I have not been disappointed with anything I have ordered from you. This wiring kit should do the trick for my flat towing project. I am sorry that I couldn’t get all of the pieces from you, the transmission pump and base plate was ordered from another company. This is my fourth camper you are helping me keep maintained and improved. 2000 Cougar 5th wheel bunkhouse,2016 Sprinter 5th wheel front living room , 2021 Nexus 31t class C and a 2016 sprinter tow behind.

Very straightforward. I followed along to one of the videos on etrailer's site and it went very easy for me thank you etrailer!

Fast shipping, good price, I buy a lot from etrailer.com. It's always my first place to shop for trailer stuff.

Received rm-164 great product,exactly what was needed for my coach and tow vehicle. No re wiring. Thank you.

My "RoadMaster 7-Wire to 4-Wire Straight Cord Kit" works like a charm. Installation was easy. Thank you!

Outstanding Customer Service. Large product inventory at great prices. Will continue to turn to etrailer for equipment in the future.
