With 45 years of experience wiring custom vehicles, we can safely say that no two electrical systems are the same. We have found that an off-the-shelf wiring harness kit is going to typically need to have substantial modifications to be tailored to your project anyway so why spend the extra money and be limited by a kit. We stock or have access to the components to build an electrical system from the ground up so we are able give you a better electrical system tailored to your vehicle.
