Most Popular Roadmaster 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

Always completely satisfied with Etrailer service and products! Jamie B is very knowledgable and courteous!

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.

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.

East to wire up.. made it a lot less headache to do without it

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.

Great friendly service & superior knowledge of the product

Ordering and shipping was fast and easy. Products arrived in good condition. I haven't installed them yet, but it all looks as advertised. Not my first order with etrailer and the customer service was outstanding as always. Why anyone would order from any place other then etrailer I cannot fathom.

The install on my Ford Maverick is clean and functional, so this is more of a customer service review... excellent customer service! During the 4-day towing set-up install, the forecast was for freezing temps and my rig was not winterized. I called in mid panic and the motorhome was moved indoors. A few months after using the tow set-up, a minor problem developed. I called and the CSR apologized and said, I can see how that might be frustrating, and a replacement cable (slightly longer) was sent free of charge.

I also purchased brackets and receivers for the tow bar. Both were as advertised and are functioning very well. The staff were also very knowledgeable and helpful. Hard to find service of this kind in today’s world.

Roadsters product worked well. I did not remove the lower dash part, and just did extreme yoga to remove and install the fuse bypass. This was the worst part. I can't believe that Honda put this fuse block in such a difficult to access location. The rest was simple. Installing the small connectors was a trick, (I also didn't use the fuse connector) but I finally got the connections in the fuse block. Drilled the hole from the outside and installed the switch. The location could have been lower and more to the left as there was a thicket portion of the dash on the back that prevented the lock nut from seating, but the switch is tight and works well. This is absolutely the way to go instead of pulling a fuse on my 2014 Honda CRV!

This product seems to be of good quality and was delivered quickly. It will not work for my application. Check you tail lights closely, my 2014 ram has LED tail lights and I am unable to find a location that will allow me to install these. The non LED tail lamps are no problem.

Product was easy to install, and worked as advertised.

My E-trailer experience was outstanding! From the great selection guide to the delivery to the installation support. The installation videos were very helpful. I had two installation issues that were answered with a prompt phone call. One call was on a Saturday morning. I highly recommend E-trailer!

Highly recommend E-Trailer for all of your towing accessories. Great product, great customer service!!

In ordering the parts I got a little confused as to exactly which kit I needed. My motorhome has combined brake/turn signal lights & the car ('03 Subaru Outback) has separate brake/turn/parking lights. Thought I needed the 6 diode kit (which I ordered) until I had all the parts here & read through the instructions for the umpteenth time (BEFORE cutting anything) & then realized what they were doing. Turns out all I needed was the 4 diode kit. Sounds like there won't be any problems returning the unneeded parts since they were never installed. Great service there! Took a lot apart in the back of the car because of the lack of space behind the tail light assemblies, but it all comes apart pretty easily. Also allowed me to route the wiring along side the stock harness. Have a bunch of 1/2" split loom here & used it. Thought I would have lots of wire left over, but I actually had to splice 2 cut offs to make a jumper long enough to get from 1 side of the car to the other. Glad the car wasn't any longer & I didn't have to make up 2 jumpers as with some of the kits! Hardest part was finding a hole in the firewall & getting the harness routed under the dash so as to not tangle with the pedals, etc. I just don't flex like I used to. Everything works fine although it was NOT a "5 minute job".

The diodes and wiring are good and worked well. But the 118158 converter produced a 3.5 volt drop such that the brake lights were as dim as the tail lights. And when a turn signal was triggered the brake lights dimmed even further. I ended up stringing a separate brake wire through the car and re-wiring my truck with a 5-wire connector.

Installed in my 2024 Chevy Trax. I ran the wire harness up through the front fender, and along the DS rocker panel. No drilling into body required. However, I purchased extra loom to better protect exposed wires next to body. Additionally, I purchased extra wire to support the DS to PS taillight connections. Finally, be advised the plastic taillight assemply is "double hulled," so once you bore through the exterior of the assembly, you will need to drill again, into the lense. On this point, and to ensure a good fit of the bulb socket, a Dremel tool was used to grind down the plastic surface, to ensure a good flat and tight fit. Finally, I used the first cut-out to fashion a cap and to seal the light socket installation. See pic.

I am very happy with this kit. It gives you everything you need to setup an independent brake light system for you toad and therefore bypassing the vehicles internal wiring and computers. I went with this setup as I did not want to complicate my wiring or damage the internal systems of the toad. IT takes sometime to install, but once done hooking up and running the system is simple as plugging in your 7way connector. Combine this with a onboard braking system, and you have the perfect system to pull your two vehicle behind your RV.

These lights have worked flawlessly for the whole 2023 camping season on my RV towed vehicle. I mount them on the rear of the roof so they are nice and high above bicycles on a hitch mounted rack.

Extremely happy with the tow bar wiring. Not one problem for the year!

have successfully completed the installation of the following items that I purchased from etrailer: > Nighthawk RM-676 tow bar > RM-524458-5 base plate > DEMCO Stay in play DM86VR > RM-152 diode wiring kit > RM-156-25 charge wire kit > RM-88400 brake switch relay kit I work slow but methodically. I had no issues other than the high degree of difficulty for a 68 y/o man working alone. This project exceeds the abilities of someone NOT mechanically inclined. There is also the need for some specialty tools. I found that feeding the wiring through the dash, firewall, and underbody was more difficult than installing the front baseplate. Overall, I am satisfied with the function of this installation. I am glad I did it myself rather than having it done.

It fits the bill--when they say universal that's correct; may not be a "factory" wiring harness but our Super Beetle is 45 yrs old.
