Wiring harnesses and cable assemblies for boat builders, engine and equipment manufacturers, RV and camper builders, and energy storage companies. Built and tested by hand in Fife, Washington.
Our harnesses go into patrol and workboats, packaged engines, heavy equipment, camper vans, truck campers, trailers, and battery systems. Send us a drawing, a sample, or a pinout, and we'll build it, test it, and ship it ready for you to install. We can handle prototyping, one-offs, or hundreds of pieces a month.

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.
On the water, on the job site, or on the road, a bad crimp is a breakdown. We build every harness like it's going somewhere extreme.

A drawing, a sample, a BOM, or a pinout. We'll review it and suggest improvements.

Cut, strip, terminate, lay out, dress, and finish, all in house.
Every circuit checked, labeled, and packed ready for your line.
