- Fit Notes
Factory Fit engine 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 original 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 harness is built for an original alternator with an external voltage regulator.
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 consult your factory service manual to determine if the front light harness for your vehicle will contain the circuits required for your project, or give our Sales team a call to confirm part numbers.Front Light Harness Generator To Voltage
