This single block diode makes it easier to get your wiring kit installed, creating just one place to connect all your wires. Carries brake and turn signals from your RV to your towed car while flat towing and prevents damage from electrical feedback.
Features:
The diagram above shows the installation of Blue Ox's tail light wiring kit on vehicles that have standard red lights that function as both brake lights and turn signals (a combined/2-wire system).
The diagram above shows the installation of Blue Ox's tail light wiring kit on vehicles that have separate amber turn signals and red brake lights (a separate/3-wire system), as well as a brake light wire that splits before reaching the tail light sockets.
In vehicles with separate turn signals, the amber signals will not function when hooked up to your RV. Instead, the tail lights will act as turn signals while flat towing. You can add a converter (C56196 - sold separately) to solve this problem.

Today we're going to take a look at the Blue Ox Tail Light Wiring Kit, with the block diode. Now when you're flat towing a vehicle, if you use this kit installed on your towed vehicle, it'll allow a motor home or RV to power the lights on your towed vehicle without having power feedback.Basically this diode block here permits electrical current to flow in only one direction. And that's from the motor home to the towed vehicle, and that'll prevent electrical feedback. This part . this kit includes everything laid out here on the table. Starts with a 26 foot long, four-wire harness.
The nine-terminal diode block. The connectors you need, all the installation hardware, nice set of detailed instructions. And again, the diode block is the part that prevents the electrical feedback, and damage that can cause to your towed car's electrical components.This kit is made in the USA. One note I do want to mention, that in automobiles that have separate turn signals, which are called a three-wire system. The amber signals will not function when hooked up to your RV.
Instead, the tail lights will act as a turn signal upon receiving communication from your RV.But that should do it, for the review on the Blue Ox Tail Light Wiring Kit, with the block diode.
