Towed Taillight Wiring

If your "application" wasn't such a secret, maybe someone could give you some insight that would help.

Thanks for all the insight. I did some research and no one seems to have a "plug and play" system for my application. They do however sell the trailer wiring kits "plug and play". My little engineering mind started turning and I am thinking maybe I can buy a trailer wiring kit for the factory plugs, and a universal diode kit and make my own "plug and play" setup. My main concern is cutting into the factory wiring harness. I'm just not a fan.

I bought a kit from e-trailer and connected to my Suzuki Samurai. Works great and I don't have to do anything to the Samurai like disconnect the battery, pull fuses, yada-yada-yada. Here's the e-trailer link to their kits. Be prepared; there are hundreds of versions! You'll need to know how many lights on the towing truck and how many on the towed for example, so the converter is the right one.
I THINK mine was plug-n-play with pigtails on the towed wiring harness that were inserted. Either that or the bulbs themselves had a pigtail.
You might just want to call e-trailer. They really made this easy for me.

There are also wiring kits that supply their own bulbs that you would install into your tail lights. Theses work separately from the vehicle, like a trailer set up.

You might get better answers for this over in the "dinghy towing" forum, but the quick simple google answer is "YES."

Hopkins makes harnesses for many/most/maybe all vehicles suitable for towing 4-down. Check etrailer.com

Hopkins towing solutions has plug and play adapters for many vehicles. I use one on my chevy 2500 and it works great.

I did this a while ago. Disconnected the battery on the vehicle in tow, then ran a jumper I made that connected my trucks trailer light harness to the trailer harness of the vehicle in tow. Worked perfectly but it was late 90's and cars had simpler wiring systems.

I was hoping for an adapter that would plug into the harness similar to how trailer light plug kits do. They tee into a plug in the harness.

If you are going to put in diodes, your going to cut the factory wire whether you get a kit or not.
