Boat Wiring Harnesses Built For Marine Projects
Marine wiring assemblies for console rewires, pontoon upgrades, bass boat electronics, trolling motors, and battery distribution.
MiniProto builds boat wiring harnesses with sealed Deutsch connectors, heatshrink ring terminals, marine tinned battery cable, tinned conductors, sealed connections, labels, and practical ABYC-style practices. We do not claim third-party approval, but we do build with the materials and documentation marine installers expect.
