Product details
FAST Fuel Injector Adapter Harnesses and Connector Kits enable easy retro-fitting of both new and old style electronic fuel injectors. New style fuel injectors can be used on vehicles equipped with older-style Minitimer connectors. Retro-fitting a Minitimer injector into a USCAR harness is also possible with a different adapter harness. Connector kits, complete with terminals, seals, and plugs, are available as well, allowing direct re-termination of existing harnesses with the correct connectors, either Minitimer or USCAR.
