Roadmaster 6-Diode Universal Wiring Kit for Towed Vehicles with Separate Lighting
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.

Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit
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.
Finished wiring and first effort to plug in red flex coil to the Jeep and the outside protection cover broke apart; very disappointing. Trying to contact Etrailer for replacement.

Tail Light Isolating Diode System with Wiring Harness
I was looking for something to add to my 2014 Equinox for tail/brake/t-signal lighting for towing behind my motorhome. This system worked perfectly , and couldn't have been easier to install. The hardest part was running the wiring from front to rear ( through frame rails and what-not ). Tail-lite hook-up was a breeze. There was plenty of wire to do the job also. Now the vehicle lites work as a trailer and does not interfere with the normal vehicle lite operation.
installed your isolating diode wiring harness 38955 also the blue ox base plate bx1126 . install was very easy with video on your site.was installed on my 2007 wangler to be towed with holiday rambler motor home.

Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 4-Pole Flat Connectors
2011 Honda Pilotthis is the only company I will buy from
It does what it says on the tin. Easily lit up my XJ so I could tow it. Only regret is that by making the connections at the rear, you don’t get the front market lights on the toad. I should have connected the running lights diode in the harness under the dash so all the marker lights come on at night.

Haven't installed yet but service was excellent

Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Wire to 6-Wire Straight Cord
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.
The installation ins ructions and video were very helpful. The wiring kit worked perfectly.
