    Custom Electrical Systems for Automotive, Construction & Emergency Vehicles.

    We mainly offer high quality wire harness manufacturing, electrical supplies and cable and wire.


We are a small family owned Business in the town of Grunthal. Our focus is in manufacturing wire harnesses to your specifications for various types of industries. We really enjoy taking the time to design, manufacture wire harness and most of all to see our product put into service that brings your creations to life.

Like most people I’m a DIYer, so having access to electrical supply’s was hard for me when only a small amount a supply was needed.  So, I have made it a mission to make it convenient for you to purchase small QTY’s of wire, cable, connectors instead of huge minimums.

Please don’t hesitate contact use with any question you may have, and we will do our best to provide you with the product or services you require.  Hope to see you in our shop soon.
