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…

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.…

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…

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…

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…

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.…

Typically 4-way wiring consists of 18 and 16 gauge wires. For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector #W787264. The part #HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.

Hello Mike. It sounds like you are wanting to add electric brakes to your boat trailer that currently has no brakes. This is possible, but you will first need to make sure that your axle is equipped with a brake flange at the base of the spindle. The…

On a 7-Way connector the suggested minimum wire gauge for the White (ground) wire, the Red or Black (power) wire, and the Blue (brake power) wire is 12 gauge. The minimum wire gauge for the remaining Green (right turn/brake) wire, the Yellow (left…
