Parts Needed to Add Electric Trailer Brakes to StarCraft Boat Trailer

You can indeed use electric brakes, but we'd recommend unplugging the trailer before backing into the water.

If you click the link I've provided, you can see what's needed to add brakes to a trailer that currently has idler hubs.

The first thing you'll need to do is determine which wheel bearings your existing hubs use. Then, find the wheel bolt pattern and wheel diameter (last two numbers in the tire size) so the new hub/drums you choose will be compatible with your existing spindles and wheels. Finding the correct parts can be somewhat like putting a jigsaw puzzle together, so if you'd care to determine the reference numbers from your inner and outer wheel bearings, as well as the diameter of the spindle where the grease seal rides (use digital caliper like # PTW80157 to find the diameter, as a ruler or measuring tape won't be accurate enough), I'd be happy to recommend the correct hub/drum. Once we know which hub/drum we're using, you can choose the correct brake assembly.

We do have all the hardware you'll need, but the specific parts needed will depend on which brake assemblies you use.

With the hubs and brake assemblies nailed down, you'll need to wire the trailer. The easiest way to do this is to use a molded trailer connector like # H20044 and a trailer wiring junction box like # 38656. The current lighting circuits on the trailer can be ran to the junction box, where they'll connect with the wires from the trailer connector. Be sure to note the trailer connector's wiring color codes listed on the product page that I've linked for you. You'll also need some 10-1-1 brake wire. Once lead from each brake magnet would connect to the brake line, the other lead would ground to the trailer frame. The other end of the brake line would run to the junction box where it would connect to the trailer connector.

You'll also need a break away kit, part # 50-85-313 and a brake controller like the best selling Tekonsha Prodigy P2, part # 90885.

If you'd reply with the information I've requested above, as well as with the year, make and model of the tow vehicle, I can provide you with specifics about exactly which parts you'll need. I've linked you to several FAQ articles and an install video that I hope you'll find helpful.
