William D - 06/22/2016I haven't installed this yet. But I know etrailer video will be of great help. 165408
dave t - 12/12/2015Work as discribed. The first time for me to use the universal kit and was a little worried about the outcome but I followed the instructions and it works great. The hardest part was routing the wire around the front end area. Wire was just enough, I recommend starting at the front end and route the wire on the passenger side. This is the side of the motorhomes 7 pin plug. Remember to stay away from the exhaust (on most trucks as mine is a Chevy 1500). Product was received within 3 days of purchase which works for me. I give Etrailer 2 thumps up for great service once again. 511182
Installation on 2018 Kia Soul 486230

JOANNE B - 09/20/2015I installed the wiring harness yesterday and it took about 4 hours. Thats actually 4 hours of work, in reality it was more like 6 hours but most of the time was trying to figure out how to route the wiring which is not the fault of the harness. Everything worked as advertised with no gotchya's or any issues which was really surprising. I installed it on a 2009 Smart fortwo Passion which I am towing behind my motorhome. My advice for anyone using this is take your time, read the directions carefully before you start and follow them step by step and you should have no issues. 281855

This isn't the first time I've installed a wiring harness and this one was a nice one (I thought). But I am having problems with the right light (both brake and running light). I've tried calling and talking to your customer support with no answer! I've found if I turn on my lights, at least the running lights all work (but not the brake light or turn signal). I'm thinking it's a grounding problem, but haven't been able to fix it so may have to try someone else's wiring harness. 608773

Easy to install and has worked flawless ly 825775
The products purchased were to allow me to tow my new Jeep Grand Cherokee behind my motorhome. Actually I had purchased a similar setup from you Five years earlier for my 2014 Jeep Cherokee Trailhawk. Both worked as advertised and I was very satisfied. 828045
Again this was an installation issue. The only video is not applicable to the 2019 Ram new version. What is not clear is were do you cut into the trucks wiring. It should be made clear in the instructions. If there is a connector in line then make the splices on the truck side of the connector not the light side. 815338
Pretty Easy Set up with Easy to View Pictures and Videos. Works Perfectly 809433
Not too difficult to install on 2020 Jeep Wrangler Unlimited Sahara. Etrailer video helped with making the correct splices to the correct colored wires. 802805

I would asbolutely buy this Roadmaster battery disconnect from etrailer.com again. I bought it in May of 2019 and had a mechanic install it. Due to a shortened travel schedule we only towed our jeep a few times and the switch failed. I called etrailer and they gave me the direct line to Roadmaster customer support who looked at a picture of the installed switch & solenoid and said it was broken because it had been wired incorrectly. They sent me a new switch, which I just installed myself. It was not difficult...and it works perfectly. Both etrailer and Roadmaster's customer support was superb. They were helpful every step of the way. I am a huge fan of both companies as a result of how they handled this transaction and follow-up. 796683
Following the enclosed instructions and diagrams made the installation easy. It has made a big difference in my motorhome traveling while towing my Silverado pickup. No more fussing with magnetic tow lights and wiring. 794957

I purchased the Roadmaster Crossbar-Style Base Plate Kit w/ Removable Arms, The Roadmaster Nighthawk Tow Bar, Quick Disconnect Crossbar, Universal Hy-Power Diode Wiring Kit, and Roadmaster Guardian Rock Guard in order to tow my 2020 Ford Raptor behind my Class A. Everything bolted on beautifully and the craftsmanship was fantastic. Ordering from etrailer was easy and the parts arrived within a few days with no problem. I watched numerous [online] videos to learn how to install everything and they saved me a lot of time. Overall, I'm very happy. 777655
