Built by hand, by people who care

Every Power 10 harness is laid out on a full-size board, routed, dressed, and finished by our team in Fife, Washington. We work from your drawings and cut lists, and we know your parts by part number.

That attention is why OEM builders come back to us with repeat orders, new programs, and the projects nobody else wants to touch.
