UNPLUG THE OLD.
PLUG IN THE NEW.

Wiring harnesses for 1990s Ford trucks — transmission, charging, and ignition. Manufactured in Canton, Georgia.

The Original Modular Replacement Harness

Every HHC harness is modular — individual sections unplug and replace independently without rewiring the whole truck. When a section wears out from heat or age, you swap that piece, not the entire harness.

What Truck Do You Drive?

Answer a few questions and we'll match you to the exact harness your truck needs. No fitment charts, no guesswork.

A Manufacturer, Not a Middleman.

In-House Manufacturing

Every harness is traced from factory originals, assembled on dedicated jigs, and tested in-house. Not mass-produced, not dropshipped, not rebranded.

Direct Connector Sourcing

We source OEM-spec connector housings direct from the warehouse. Ford discontinued them — we didn't.

Proper Construction

TXL wire, heavy-duty nylon corrugated conduit, Ford OEM-spec connectors. Built on a jig, not in a bag.

Real Warranty

3-year HHC warranty. Not a 30-day parts store return policy.
