This custom harness will allow you to use your own parts for your own Flex Fuel project. Works with GM Flex Fuel sensors which work by sensing the ethanol content of the fuel being delivered to the engine, which allows the vehicles computer to adjust the tune accordingly for maximum performance with the given fuel. This happens via real time communication to ECU, so it is a seamless adjustment with no user action or input required. This kit is assembled with OEM style connectors, professional wire crimping, and high quality Tefzel ETFE wire.
