1966 Ford Mustang Main Under-Dash Harness

This premium under-dash wiring harness with relays is exclusively designed to look like an OE harness but with a modern 12 circuit ATC fuse block and relays for improved performance and reliability. Each harness is tailored to exact specifications with proper molded connectors and correct colored wires for a plug-and-play installation. There's also room for expansion with spare hot and keyed terminals in the fuse box. Does not include separate wiper harness.
