- 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.
Air conditioner wiring is often a separate add-on item that runs in parallel with the remainder of the chassis harness. In most situations, the AC harness is a single piece with connections for the compressor and blower motor. Some vehicles do require a two piece AC harness, so please verify selections for your project prior to purchase. Connections vary significantly from vehicle to vehicle, so we recommend using a factory assembly manual to assist in this installation.
