What happens if you get a trailer with electric brakes and you don't have the brake controller? Will the brakes on the trailer just not work or will they lock up? I need to know asap as I'm off to pick a trailer up quite a ways from home.

With no power the brakes should not activate.

If the trailer has a battery with a breakaway cord they may activate if the pin is pulled.

The brake will just NOT work if the trailer is wired correctly.

I SURE HOPE THIS IS A EMPTY TRAILER!:eek:

As long as the pin is still in the "break away" control the wheels will not lock up. I need to move my trailer to mow around it and I do it with my Gator with out any lock-up issues. :)

If you get a trailer with electric brakes and don't have a brake controller the trailer brakes will not work. The lighting will work if its properly wired to the truck plug. The lighting usually requires only four wires (left turn, right turn, parking lights, and ground). The trailer brakes require power from a brake controller mounted in your truck. There is a safety brake on the trailer that will work. It consists of a small battery wired to the brakes through a breakaway switch that applies power to the brakes should the trailer become disconnected from your truck and the pin pulls out of the breakaway switch. It would apply 12V to the brakes to lock them up and stop the trailer. The bad feature of this is that unless you have a way to keep that trailer mounted battery charged you have no idea if it is any good or how much voltage it has should you need it. You could probably get away without the brake hookup if you are going to pick up the trailer and tow it back empty but get a controller for your truck as soon as you can. They are reasonable in price and can be installed in about an hour or so.

Do be sure you have compatible wire plug on your truck before you set out. The trailer probably has a six or seven pin hookup on it if it has brakes. You can adapt a seven to a six or four but not the other way round.

I can't count the times a customer has come to my store looking for an impossible plug. (4-7) I try to tell them in as nice a way possible they're going to kill someone. (8

Any good trailer shop will have adaptors. I use one with a 2 wheel (no brake) cargo trailer 4 way plug to a 7x on the dump. Also a 7x on a tandem to a 4x on a pickup for empty moves. Used the tandem once to drag it home, The smaller probably once per year. Cheaper to make them but these are molded & no tangle of wires.

I picked up the trailer the day I posted this without incident. I was setup for any wiring configuration. And I ordered a Prodigy controller it should arrive tommorrow. Thanks for all the replies.
