In order to convert the surge brakes on your Triton Snowmobile Trailer to electric assemblies, you will need the brakes themselves, wiring, a breakaway kit, and possibly hub and drum assemblies if you do not already have them. I have attached a fantastic article on adding electric brakes that you can also reference. The article details every item you will need, along with helpful installation tips.

If you already have drums on the trailer, you will want to measure their depth and diameter to ensure you choose the correct size electric brakes. For example, the etrailer.com Electric Trailer Brake Kit # AKEBRK-35-SA features brake assemblies that measure 10 inches x 2-1/4 inches and are typically found on 3,500 pound axles.

Once you find the right brake assemblies, you will need to wire the trailer in order to power the brakes. If the trailer doesn't already have a 7-Way connector, you can install one with # HS381-9000, which attaches to a junction box to make wiring everything a bit easier. You can use ring terminals like # 44-5310A to connect the wiring and 10 gauge wire like # 10-1-1, which is sold by the foot, to run the wire from the junction box to the trailer's brakes.

You will need to run the wiring to each brake assembly. Each assembly will have 2 wires coming out of the back, one of which will be attached to the trailer for ground and the other will connect to the above mentioned wiring on the trailer. It does not matter which wire you use for which purpose on the brake assemblies.

The trailer will also require a breakaway kit. The Hopkins # 20099 is a great choice. This will engage the trailer brakes in the event that the trailer is separated from your tow vehicle.

Since it sounds like your truck already features a brake controller, you should be all set on the vehicle side, as long as it has a fully-functional 7-Way connector.

If you are able to give me some more information on your trailer, such as the size of the drums and axle capacity, I will be happy to make some more specific recommendations.
