What is the Difference Between a 4-Way and 7-Way Trailer Connector
Question:
What is difference between a 4 pin and 7 pin trailer connector?
asked by: Carl Z
Expert Reply:
A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground.
A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer brakes (requires a brake controller in the vehicle), and a reverse light or auxiliary power circuit.
There are other types of connectors as well. I have included a link to our help article that shows and explains the various connector types.

Totally new to this, so go easy ;) Doing a ground-up rebuild of a 4'x8' single axle utility trailer that will have a basic lighting setup, but I would also like to install a powered winch (i.e. Badlands 2500 from Harbor Freight). I would like to wire the winch into the lighting harness (or get a harness that includes the necessary wiring) so that when the trailer is plugged in to my truck (has 4-pin and 7-pin connections) everything will work. What's the best way to go about this? Is there a 7-pin harness I can install and just hook up all the lights and the winch to? That would be ideal. If not, I have a 4 pin harness already; how can I tie the winch in to that?

My 2019 Minnie Winne has a 7 pin connector in rear for flat towing. What wiring harness/connector do I need for my 2018 Wrangler Unlimited? I want to get the patriot II, can I keep it plugged in recharging while driving, through the RV connections or do I need to install a 12v hot wire for the Patriot II?

I just bought a 2019 Ford Ranger Lariate w/ tow package in March. Ive towed my camper twice; it seems the trickle charger from the 7 pin is not working (so the mini fridge in the camper wont run to keep things cool while traveling.) If the tow package missing this feature, or is there something I have to turn on?
