Designed for the Original Externally Regulated Alternator

One of the most important fitment details for American Autowire part 22220 is the charging system configuration.

Original External Voltage Regulator

This harness is designed for Chevrolet pickups retaining an original-style alternator with an external voltage regulator.

Unlike modified alternator-conversion harnesses, part 22220 maintains the original externally regulated charging system configuration.

What If My Truck Has an Internally Regulated Alternator?

If your truck has been converted to a GM SI-series internally regulated alternator, American Autowire offers modified versions of this harness.

These include:

• 22220DI: Driver-side internally regulated alternator

• 22220PI: Passenger-side internally regulated alternator

Choosing the correct harness depends on your alternator type and mounting location.

Why Does the Alternator Configuration Matter?

Original externally regulated alternators and later internally regulated alternators require different wiring arrangements.

Selecting the correct harness helps ensure compatibility with your truck's charging system and avoids unnecessary wiring modifications.

Designed for Factory Gauge Instrumentation

American Autowire offers different front light harnesses depending on the original instrument panel configuration.

Factory Gauges

Part 22220 is specifically designed for trucks equipped with factory gauges.

Trucks equipped with factory warning lights require a different front light wiring harness.

Why Does Instrumentation Matter?

Factory gauges and warning lights use different electrical configurations.

Choosing the correct harness helps maintain compatibility with the truck's existing electrical system.

If your truck has been converted from warning lights to gauges, verify your current wiring configuration before ordering.

Designed for Trucks With Factory Side Marker Lights

This harness is designed for Chevrolet pickups equipped with factory side marker lights.

The side marker configuration is an important consideration when selecting a replacement front light wiring harness.

If your truck has undergone body modifications, lighting conversions, or other electrical changes, confirm the existing wiring configuration before ordering.

Why Replace Your Chevy Truck's Front Light Wiring Harness?

After decades of use, original wiring can develop electrical problems caused by deteriorated insulation, corrosion, vibration, and previous repairs.

Replace Aging Factory Wiring

Original wiring insulation can become brittle or cracked, while electrical terminals and connectors may deteriorate over time.

Replacing the harness provides an alternative to repairing numerous damaged wires individually.

Restore Front Lighting Connections

American Autowire explains that most front light harnesses include circuits associated with:

• Headlights

• Parking Lights

• Front Turn Signals

• Horn and Horn Relay

• Charging System Connections

This particular harness is also designed for trucks equipped with side marker lights.

Exact circuit coverage varies by application. Consult your factory service manual to confirm the circuits included in your truck's harness.

Maintain Original-Style Wiring

American Autowire's Factory Fit products are designed for classic vehicle restorations where maintaining original-style electrical connections and routing is important.

Fully Assembled for Installation

The harness arrives assembled and taped, connects at the original firewall location, and follows factory-style routing through the engine compartment.
