Need 7 pin trailer hook up help / info

[smokinjoe]

So I have a 4 pin on my van but the new trailer is a 2 axle 30ft with a 7 pin.

Can I just get a converter to 7 pin? Do I need a brake controller? Does the trailer need a fresh battery to work the brakes?

I only every plan to tow it 7 miles down the road but would like to get it set up properly.

Any insight would be appreciated.

7 Pin implies that the trailer has brakes, backup, and/or charging circuits.

30 foot - you absolutely want brakes. There's a member on the site selling a Prodigy P3 controller - it's an awesome controller. I'd buy that and wire your TV for brakes.

Seems right in your wheelhouse.

7 miles? Depending on the tow vehicle (if the brakes are good enough) I suspect you may be able to get away without a brake controller. But I imagine the stopping distances will be ... long.

Grand rental station has a module that plugs into the 4 pin and has a brake controller built in with a 7 pin output.. If I remember right it had magnets to the trailer .

You get a wireless remote with it to adjust the brakes.

I used it when I rented a skidsteer/trailer from them before I bought a truck a OEM controller.

Brake controller, yes. Even in a seemingly short 7 miles, chances are you will run into a situation where you will want that extra braking power on tap.

How heavy is the trailer & what's your tow vehicle?


While I don't really recommend it due to the additional risk involved, I've begrudgingly towed my 4-5,000 pound 14 footer with brakes disabled because I needed to replace them before. I just stayed extra vigilant to avoid any surprise quick stops. It can be done, but yes, anything can happen.

Only 7 miles? Be smart and safe and everyone will survive just fine. Don't speed and leave tons of following distance and prepare for steep down grades.

This. If it’s a cargo van they’re over 5000 lbs and the 2500’s have plenty of braking power, but a 30 ft trailer could weigh a lot.

Pretty sure the van in question is an GMC/Chevy Astro Van if that helps with anyone's advice
