FR3 Break Controller

If I want to put a break controller on my FR3, is it prewired? I'd like to do it myself if it's just a matter of connecting it. Or do I need to have it done by the pros?

Thanks.

Steve

Hi Grotto. If you're referring to the toad brake controller, the FR3 is only prewired from the 7 wire plug to the tow vehicle ( either a 6 or 4 wire connector). The brake controller is a separate system that's wired to the toad. When wired, it will be connected to the FR3 brake lights when the pigtail is connected. There are many different types of brake controllers on the market. Depending on which one you choose will dictate if you do it yourself or take it to a pro. I bought a SMI Stay-in-Play Duo and plan on having a pro install it in my Wrangler.

I have a 7 plug connector at the hitch receiver. Oddly, I connected my tow dolly and the break was applied by default. I drove one mile (luckily a test run) and the tow dolly nearly caught on fire because the breaks were so hot. The grease started in the axle got so hot it shot out of the points. Still trying to understand the damage there.

I figured I should have a break controller installed since something isn't wired right at the hitch receiver if the breaks are being applied by default.

Thanks for any help.

Regards,

Grotto

I have a Prodigy P2. Its plug and play using one of the Ford harnesses.

I wasn't aware you were using a dolly to tow your "toad". My guess is that towing a dolly would be like towing a travel trailer (but of course much smaller). A good tow dolly should have surge or electric brakes. A Prodigy P2 is a good controller for electric. I'm not that familiar with surge brakes but if I'm not mistaken they operate on inertia, when they feel the vehicle braking. And, since the lights are outward of the tow vehicle, I don't believe the dolly needs a plug to the vehicle. If I'm wrong, I'm sure someone will jump in here.

Do you know what it will run me to install a break controller? Is the FR3 prewired?

Thanks

No, the FR3 is not prewired for a brake controller.
A Prodigy 2 is installed into your truck/mh. I had the dealer that I bought my previous TT from and they charged me $50 to install it. If you have a regular repair shop that you've been going to, they can do it for you.

I think I'm not explaining it correctly.

I have a Tow Dolly with electric brakes. The tow vehicle will ride on the tow dolly with two wheels on the dolly and two on the road (the back two). My vehicle brakes aren't going to be in play here.

When I press the brake in the RV, I want the electric brake on the tow dolly to activate. The wires to control the tow dolly brake are connected at the hitch receiver when you connect the trailer lights.

Maybe I need a different type of brake controller than what you have for a TOAD.... Sounds like its an entirely different setup. Guess I better just take it in...

You explained it just fine grotto69. The Prodigy will need to be installed under the dash of the mh and wired into the trailer plug circuit at the rear so that when you plug in the dolly, it'll activate when the mh brakes are applied. The Prodigy should have come with the proper wiring and plug for under dash installation.
Like I said, I had mine installed. It's fairly simple for the pro. :-)
You're correct. The controller for my toad is totally different than yours.

If you have the Prodigy mounted in one vehicle you can just buy another mount for the motorhome and swap the head between vehicles. I plan on moving mine between my truck at home and the RV when I need it there.
