  • The wiring harness has been our core business since 1987. Sumitomo Electric Wiring Systems designs and manufactures the highest quality and most reliable wiring harness products for the automotive industry.

    A wiring harness is an organized set of wires, terminals and connectors that run throughout the entire vehicle and relay information and electric power, thereby playing a critical role in “connecting” a variety of components. Power and information travel through this network much like the circulatory and central nervous systems of the human body.

  • As cars continue to provide advanced functions, their component parts increasingly require electronics to save space and meet other requirements. Experts at efficient design and configuring complex circuits, SEWS creates wiring harnesses that contribute tremendously to the development and advancement of car manufacturers around the world.

    This is my basic guide to making a wiring harness. This is one of those things that can be really frustraging, but if you take your time it will be much less painful. Every harness is different, so I'm going to show you the basics. The rest you will have to figure out - that's the fun part!

Simple enough. Speed Scene Wiring can build from scratch or we can modify you exsisting wire harness. The CPI wire harness above is from a donar 1994 S10 that didnt mind giving up its engine, due to the fact that the owner faceplanted it into a tree. Then sold the engine to a customer of mine, who has now placed the engine into a 35 Ford High Boy. The wire harness above has full emissions, 4L60E trans, 2 knock sensors and an ALDL connector.
