Universal 21-Circuit Kit

This 21-circuit wiring harness kit is designed for classic and custom vehicle builds. It supplies labelled circuits for ignition, lighting, accessories and convenience features. The kit suits restorers, hot-rod builders and anyone rewiring a GM, Ford, Chrysler or Mopar platform.

Replaces Aged Factory Looms

It replaces brittle, colour-faded original wiring that no longer carries load reliably. The jump is worth it when the existing loom has cracked insulation, missing circuits or mismatched repairs. Seventeen included fuses give each circuit dedicated over-current protection.

Integrates With Existing Systems

The harness connects to the vehicle’s switches, gauges, lights and accessories using standard colour-coded leads labelled every five inches. High-conductivity copper cores resist corrosion and handle the electrical demand of added components. Professional installation is recommended to match the universal circuits to your specific chassis layout.

Questions about this item

What fuse block dimensions and mounting holes does the 21-circuit harness need?

The kit uses a standard 17-fuse block; no specific dimensions or hole pattern are provided, so verify clearances against your firewall or dash opening before drilling.

Which step do installers most often miss when wiring the labelled 5-inch sections?

Failing to match each label to the correct circuit before crimping; the harness covers hom, fan, dome, hazard, radio, lighter, locks, brakes, headlights, trunk, gauges, backup, cruise, wipers, choke, coil, A/C, fuel pump, windows and turn signals.

How often should the copper-core wires and fuse holders be inspected or replaced?

Inspect connections and fuse clips annually or after any electrical fault; replace any wire showing corrosion, heat damage or brittle insulation to maintain conductivity.
