Tow vehicle connector...Which one?

[Woodstramp]

I currently use little 4-wire connectors on my utility trailers. That works great for those trailers. Handles the brake/turn lights.

The camper I'm trying to build has other electrical considerations and I'll need to take care of. Not only will it have brake/turn circuit it will have electric brakes. I'd also like to allow for a charging circuit between the tow vehicle and the camper. (Camper battery low...switch on that circuit....crank tow vehicle and charge the camper's 12v system)

Is there a connector that can handle that many circuits or will I have to use two 4-wire jobs?

look at a 6 pin or 7 pin trailer plug. You may have to run some additional wiring in the vehicle to support either of those.

I am building a 7 pin in mine. I will have electric brakes, onboard battery etc. Pretty much the same set up you have.

I lucked out because Mopar makes a 7 pin wiring harness for my Jeep that is a simple install.

My truck and car have a quick connect for either type of connector. You can get them at U-haul if your dealer doesn't have one. I had U-haul redo my truck because it was having issues. My Nissan dealer and my car done with U-haul...

7 blade RV style connector is sort of standard on Pick ups and large trucks used as tow rigs....

I even converted my Jeep to 7 pin RV so IF I ever tow my car carrier I have at least a charged battery on brakes for a "break away" and when my TD is done I will have 12 volts available at plug for trailer battery charging when on the road (even wired it with a relay so it shuts off 12 volt to trailer plug when ignition is off)...

Thanks for all the replies. Looks like the 7 pin is the way to go.

One thing to remember is that adapters from a seven to a four pin are easy to find, hard to go the other way.
