- Fit Notes
Factory Fit front light harnesses are manufactured according to the original General Motors specifications. Each part number is fully assembled, taped and ready to install upon arrival. This harness will plug into the firewall in the factory location, and will follow original routing in the engine compartment. A combination of the engine and front light harness accomplish most functions under the hood of an early GM vehicle. This front light harness is modified for a GM SI-series internally regulated alternator installed on the passenger’s side of the engine compartment, and will not include external voltage regulator wiring. These harnesses are generally available for drivers side (DI) or Passenger side (PI) alternator mounted configurations. It is also suitable for a one-wire internally regulated alternator, but the two wire SI-series connector should not be used when installed with a one-wire alternator part.
Front light harness design can change significantly from year to year, but most harnesses include circuits for the charging system, park and turn indicators, headlights, horn and horn relay.
Please reference your factory service manual to determine if the front light harness for your vehicle will contain the circuits required for your project. American Autowire also offers a number of adapters for other GM alternators. Please consult our Sales team for additional information or to confirm part numbers.
