- 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 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.
Engine harness design varied significantly from year to year, but most will contain wiring for the ignition system, starter, heater blower, and temperature/oil pressure sender wires if applicable. Some vehicles used a capillary tube to provide an oil pressure reading, so these will not be included in a wiring harness. On vehicles with ignition points, the circuit feeding the ignition coil was designed with some resistance to extend the life of the ignition point set. Modern electronic ignition systems or High Energy ignition (HEI) systems do not require resistance in the circuit, so it is recommended that a harness modified for HEI be ordered if the ignition system has been upgraded. In most cases these harnesses are available in our catalog and feature unique part numbers.
Please consult your factory service manual to determine if the engine harness for your vehicle will contain the circuits required for your project, or give our Sales team a call to confirm part numbers.
Factory Fit dash harnesses are manufactured according to the original General Motors specifications. Each part number is fully assembled, taped and ready to install upon arrival. The dash harness is almost always the largest harness in a vehicle, and (for vehicles 1957 and newer) will include a new fuse box that accepts the original style glass fuses.
Dash harnesses are frequently available in either gauge or warning light configuration. Cars with factory gauges typically include a temperature gauge, oil pressure gauge and an ammeter. Vehicles with a warning light dash do not have in-dash gauges for these items, but rather bulbs that illuminate in the event the vehicle overheats or has low oil pressure.
Early Camaro and Nova models have console gauges, which are addressed by standalone console harnesses. These harnesses are not interchangeable, so please verify the option present in your car before placing an order. If in doubt, do not hesitate to reach out to our Sales team for assistance!
