Important: American Autowire lists part 23445PI for 1969–1972 Chevrolet pickups. Verify compatibility with your specific truck series, instrumentation, side marker configuration, and alternator before ordering.
Designed for Passenger-Side Internally Regulated Alternators
One of the most important features of American Autowire part 23445PI is its modified charging system wiring.
Passenger-Side Alternator Mounting
This harness is designed for a GM SI-series internally regulated alternator mounted on the passenger side of the engine compartment.
Trucks equipped with a driver-side mounted alternator require a different harness configuration.
Internally Regulated Alternator Conversion
Original 1969–1972 Chevrolet pickups commonly used externally regulated charging systems.
When converting to a compatible internally regulated alternator, the original external voltage regulator wiring is no longer required.
American Autowire has modified this harness specifically for that conversion.
External voltage regulator wiring is not included.
Compatible GM SI-Series Alternators
This harness is designed for compatible GM SI-series internally regulated alternators from the manufacturer's specified 1985-and-earlier applications.
Verify your alternator model and connector configuration before ordering.
One-Wire Alternator Compatibility
American Autowire also identifies this harness as suitable for a compatible one-wire internally regulated alternator.
When using a one-wire alternator, the supplied two-wire SI-series connector should not be connected.
Always follow the alternator manufacturer's installation instructions.
Designed for Factory Warning-Light Instrumentation
American Autowire offers different front light harnesses depending on the original instrument panel configuration.
Factory Warning Lights
Part 23445PI is specifically designed for trucks equipped with factory warning lights.
Trucks equipped with factory gauges require a different harness.
Why Does Instrumentation Matter?
Factory warning lights and factory gauges use different electrical configurations.
Selecting the correct wiring 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.
Includes Provisions for Factory Side Marker Lamps
This harness is designed for Chevrolet pickups equipped with factory side marker lights.
American Autowire offers separate wiring harness configurations for trucks without side marker lamps.
If your truck has undergone body modifications, lighting conversions, or other electrical changes, confirm the wiring configuration before ordering.
Why Replace Your Chevy Truck's Front Light Wiring Harness?
After more than five decades, 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 terminals and connectors may deteriorate over time.
Replacing the harness provides an alternative to repairing numerous damaged wires individually.
Restore Front Lighting Connections
Depending on the original vehicle configuration, American Autowire front light harnesses commonly support circuits associated with:
-
Headlights
-
Parking Lights
-
Front Turn Signals
-
Side Marker Lights
-
Horn and Horn Relay
-
Charging System Connections
Exact circuit coverage varies by application. Consult your factory service manual to confirm the circuits included in this harness.
Maintain Original-Style Wiring
American Autowire's Factory Fit line is designed for classic vehicle restorations where maintaining the original wiring layout is important.
Upgrade Your Charging System
This modified harness accommodates a compatible internally regulated alternator while eliminating the original external voltage regulator wiring.
Fully Assembled for Installation
The harness arrives assembled and taped, connects at the original firewall location, and follows factory-style routing.
