For over 40 years our family-owned business has been making the finest authentic wiring harness systems for antique automobiles. We offer everything except spark plug wires and battery cables.

Our experts give great care in filling your order. One expert is assigned per order and takes the order from assembling the data package – to prepping the wires – to assembly of all the harnesses and parts – to the shipping procedure. We have quality checks at each step of the process. Our reputation has been built on our quality hand-crafted wiring harness systems and the prize winning automobiles to which they contributed. We would be honored to have the opportunity to assist you with your restoration. 

Every wire harness system is truly ‘made-to-order’! We do not stock any, we make each one upon receipt of the order. Please allow adequate time when placing your order. We work on a first ordered, first served basis. Due to the huge demand for our wiring harness systems, our production backlog can run up to 6 months, depending on the time of year.

Our wire is specially manufactured with a modern self-extinguishing PVC core insulation, covered by authentic cotton braiding and lacquer coating. The color code is exactly as indicated in the original electrical schematics. Wire ends are numbered with removable adhesive numbers that correspond to our data package. Terminals are crimped and soldered for the best mechanical and electrical connection. Neoprene rubber sleeves, as originally specified, are installed on the terminals. The wires are assembled into a harness utilizing an original factory harness as a reference. We cover the completed harness with the proper materials for your automobile.

We try to make installation a simple mechanical process for even the amateur restorer, by supplying a detailed data package with each harness system. The data package contains – a copy of our limited warranty, general instructions on how to install the wiring, a diagram explaining the wire color codes, a detailed harness listing showing wire number, color code, and function, some systems include special component instructions and/or assembly diagrams for wire & conduit kits. A wiring schematic and any other information we have on your automobile from the National Service Manual (used for garage’s repair) is also included. You will remove the old harness, transfer any needed components to the new harness, put in the new harness, and use the detailed harness listing to connect the wires. If you have questions when installing the wiring system call us and we will do our best to help.

Our job is not done until everything is in and all systems work. We realize that there are varying degrees of restoration involvement. For those who would prefer to fabricate their own harness as well as install it, we offer a complete line of authentic braided wire and harness materials. A braiding (covering) service is also available for your completed harness.

Thank you,
