Part Numbers


The following part numbers are specifically applicable to 86-89 TPI systems with a MAF sensor. If the harness you are working with has relays, etc attached, they can be used as is. If you are missing any components, we suggest you try to obtain the specific pieces from a dealer, after informing him of the specific year, and model of the wiring loom you are working with. If you are not sure of the year or model, the following is a list of GM part numbers that work with the applicable notes. When specific years and models are indicated, this is per GM parts manuals. If we are aware of interchangeability, it is so noted after each item:

Powertrain Control Module (PCM)
The PCM is a programmable computer and does not contain a EPROM or calibrator. The PCM contains a Electronically Eraseable Programmable Read Only Memory (EEPROM), which must be programed before being placed in service. The EEPROM can be programed for any engine / transmission combination. PCMs are Sequential Port Fuel Injection (SEFI).
