Type A Towed Car Installation

Blue Ox Block Diode Diagram - Type A

The diagram above shows the installation of Blue Ox's tail light wiring kit on towed cars that have standard red lights that function as both brake lights and turn signals.


Type B Towed Car

Blue Ox Block Diode Diagram - Type B

The diagram above shows the installation of Blue Ox's tail light wiring kit on towed cars that have separate amber turn signals and red brake lights, as well as a brake light wire that splits before reaching the tail light sockets.


In automobiles 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 upon receiving communication from your RV.


Type C Towed Car

Blue Ox Block Diode Diagram - Type C

The diagram above shows the installation of Blue Ox's tail light wiring kit on towed cars that have separate amber turn signals and red brake lights, as well as a brake light wire that does not split before reaching the tail light sockets. This installation requires you to split the brake light wire.


In automobiles 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 upon receiving communication from your RV.

Video Transcript for Review of Blue Ox Tow Bar Wiring - Splices into Vehicle Wiring - BX8811

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.

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. 40930

This kit is great. It allows you to use all of the running lights on the tow vehicle, not just the brake and turn. Makes for a very professional looking installation. 11966

  • Installing Blue Ox Tail Light Wiring Kit with Block Diode on Towed Vehicle

  • If you are not planning on towing your Jeep really often I recommend using magnetic lighting like the RoadMaster Standard Magnetic Tow Lights part # RM-2120.

I called my contact at Blue Ox and they told me that you can use the Blue Ox Tail Light Wiring Kit, part # BX8811, although we do not have any information about this kit and installation on a your Jeep.

  • Removing Diodes From Lighting Used For Flat-Towing 2003 Acura TL
  • In order to remove the diodes from your Acura, you can do a couple things. If you want to remove the wiring harness altogether, simply trace the wires from the connector at the front of your Acura and find each diode used for your vehicle. The diode should be installed very near the tail lights. Use a circuit tester like part # 3808 and find the wire that shows current only when the left turn signal is used. Remove the diode and then use a connector to reattach the wires that the diode...
