Sample Listing Of Our Products



Standard Molded Connectors



We supply wire harnesses and molded connectors for 4 of the top 10 trailer manufacturers in North America, including #1!

Our complete wiring harnesses and connectors include 7 Way Molded Connectors and Breakaway Kits with or without a charging system.

How can I use the molded 7 way connector and still wire my trailer with the specific needs I have?
Our molded 7 way connectors can have ring terminals installed so you can wire it to a standard terminal strip mounted to your trailer frame. These ring terminals can be of various stud size to accommodate the terminal strip you decide to use. They can also be heat shrink sealed to deter any corrosion causing the terminal to break off the wire as the trailer ages.

Why molded trailer wiring harnesses?

Molded Trailer wiring harnesses afford you the complete weather proof product your trailer requires. Our molded 7 way connectors are waterproof and more durable than those plastic 7 ways you may be wiring to your trailer yourself.
