Wiring

That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary.…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

A 4-Way trailer connector has the basic lighting functions only; running lights, left turn signal and brake lights, right turn signal and brake lights, and ground. A 7-Way has these functions and a 12 volt circuit, a circuit for electric trailer…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…

Hey Robert! Ideally you're going to get 12V all the way back to the brakes but that typically doesn't happen. What exactly is the issue? Are they not working at all? At 8-9V I would expect them to have most of their functionality to a point…

Yes, 14 gauge wire seems too small. I would go with 10 or 12 gauge. For 10 gauge you can use #10-1-1 and for 12 gauge use #12-1-1. These wires are sold in increments of 1 foot. So if you needed 20 feet of wire you would enter 20 in the quantity box.…

Trailer wiring generally uses 16 gauge wire, part #16-1-1. However, with a long trailer like yours you may want to go with a larger like 14 gauge #DW07550-1 or even 12 gauge #12-1-1. Each size is sold by the foot. You will need to have the lights at…

The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th…

If your trailer has 7 wires running all the way back to the brakes, then yes, you can tap into the existing wiring. Each of your new brakes will have two wires for the brake magnet. One wire is for 12 volt power to the brake magnets and the other…

I would certainly recommend the 1/2-inch wire loom #459075-1. It will hold two jacketed 2 wire 10-gauge wire and three jacketed 2 wire 12-gauge wire. See pictures to the right. In addition, I was able to fit comfortably eleven individual 16-gauge…

Hello Merle, thanks for reaching out. The Hydrastar Disc Brake Kit #HSE7K-T1 you were looking at is for a standard 7K axle. The hubs use the #25580 inner bearing, #14125A outer bearing and #GS-2250DL (2.25" ID, 3.376" OD) seal. Most 6K…

The only difference between 7-Way Utility and 7-Way RV is the color of the wires. The pin outs are the exact same so either would work just fine with the other. If you check out the picture I attached you'll see that the functions are all the…
