Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 4-Pole Flat Connectors
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.

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.

Blue Ox Tail Light Wiring Kit with Block Diode
Haven't installed yet but service was excellent
Worked perfect for setting my 2001 Jeep Wrangler up for flat towing behind my Motorhome. The instructions were clearly written, the diode was clearly marked and all the connectors were there to make this wiring job simple.

Blue Ox 4-Diode Universal Tail Light Wiring Kit for Towed Vehicles
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.

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.

Demco 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Way Adapter Cord
etrailer was extremely helpful in getting me parts to flat tow our 2023 Jeep Wagoneer. More specifically, Noah took the time to research the required parts, offer technical guidance, and follow up to ensure I was taken care of. Top notch service which was much appreciated.
Needed new wiring and diodes for my 2023 Jeep Rubicon. ETrailer makes it so easy to set up all the wiring for flat towing.

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!!

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 Universal Hy-Power Diode Wiring Kit
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.
