Tips on selecting the proper type of fuel injector connector. Fuel injector connectors are susceptible to deterioration due to aging, and wear and tear. A fuel injectors location on the engine exposes them to intense heat, vibration, and chemical fumes. Over time, these will cause the connectors’ nylon body to deteriorate and eventually break.PCM Connector: Blue (C1) 1996-1997.
