Our top-of-the-line EZ Wiring 21 harness covers 21 circuits with 18 fuses on a compact mini fuse panel, so you can wire a full-featured street rod or custom truck with one kit. It handles horn, fan, dome and trunk lights, hazards, radio, cigarette lighter, door locks, brake, headlights, gauges, backup and cruise, wipers, choke, coil, A/C, electric fuel pump, power windows and turn signals. It supports modern GM and aftermarket steering columns, including Flaming River and Ididit. Lengths are sized for a long bed pickup. Every wire is color coded and labeled along its length, and the high temp GXL 125 jacket resists grease, oil, gas and acid, which makes install and troubleshooting a lot easier.
