Why This Harness Over Anyone Else's
Every other option is a universal harness you have to adapt. That means guessing at wire colors, extending short leads, splicing in circuits for gauges, HVAC and power accessories, and chasing ground problems. This harness was engineered from the ground up in our own build shop for the 1961–66 Ford truck, and it is designed to work with the Ford Racing Control Pack, so the truck harness and the engine harness work together from day one.
Fits 1961–66 Ford F-Series 2-door trucks only.
Clean Power, Zero Headaches
Your classic Ford needs wiring that works with modern engines. This complete harness was born in our own build shop, refined through countless Coyote and Godzilla swaps until we nailed the perfect balance of reliability, serviceability, and clean integration. Plan on approximately 40 hours of install time with this FFG exclusive kit.
