About Us

Pre Built DIY Wire Harness Kits 


Our harnesses will safely and reliably accommodate your lighting, cooling, stereo & communication needs.  They are specifically designed to provide the appropriate wiring from the power source to the switch ending at the location of the component. No additional wiring, connectors or parts are required, which will drastically reduce the amount of time it takes to install a harness, and virtually eliminates routing & circuit overloading errors.

     Custom Plug & Play Harness


Customer specific plug and play harnesses. If one of our pre-manufactured harnesses does not suit your needs we are here to help. Whether you are racing or running the trails, you design it for your needs, we build it, send it to you, and provide installation support. We can build vehicle specific custom wiring solutions with a variety of options. Pick the wire protection, connectors, wire type & circuit protection type.
