Injector Plug and Wiring Requirements
The ish01-0650h injector set requires an injector plug conversion at the vehicle wiring harness when using the included PGTUSC8 pigtails. The pigtails can be soldered into the harness to replace the existing injector plugs. For an installation that does not require cutting or soldering the harness, optional PADPUtoJ8 plug-and-play adaptors can be purchased to convert between the injector and vehicle harness connections.
This connector configuration allows Fuel Injector Clinic to provide brand-new, unused injectors for its performance applications rather than relying on remanufactured or core-program injectors. For aftermarket fuel systems or other non-standard installations, contact Beefcake Racing before ordering to make sure you receive the correct injector configuration for your setup.
