FAST Fuel Injector Adapter Harnesses and Connector Kits enable easy retrofitting of both new and old style electronic fuel injectors. New style fuel injectors can be used on vehicles equipped with older style Minitimer connectors. Retrofitting a Minitimer injector into an 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.
