Installation

 

Installing an eFlexFuel capability kit requires some auto repair knowledge as well as a variety of hand tools and a multimeter. With a little bit of know-how, install will take 2-3 hours (depending on your vehicle). However, if you bring your vehicle to a local repair shop, they can likely install the kit in 2 hours or less. Below is a brief overview of the installation process. Use Caution: Always avoid parts with high voltage within the engine bay. You can find more detailed instructions here.

  1. Depressurize the fuel system and remove all necessary covers, etc. to gain access to the fuel injectors.
  2. Disconnect the fuel line from the fuel rail.
  3. Install the ethanol sensor in the OE fuel line, using the supplied quick connectors. Or use the fuel line that is supplied with the kit (if needed).
  4. Make sure that the fuel line and the ethanol sensor are properly fastened and there are no fuel leaks.
  5. To install the wiring harness, first verify the OE fuel injector connector polarity with a multimeter.
  6. Based on the measured fuel injector polarities, assemble and connect the supplied male fuel injector connectors to the eFlexFuel wiring harness.
  7. Connect the eFlexFuel wiring harness to the OE fuel injector connectors (both to the injector wires from the ECM and the fuel injectors). Connect the two analog input wires to the engine’s sensors. Reminder: Avoid parts with high voltage within the engine bay.
  8. Place the temperature sensor within close proximity of the engine block and connect the ground wire to a sufficient ground terminal.
  9. Connect the ethanol sensor connector to the eFlexFuel wiring harness.
  10. Finish installation by connecting the control unit to the wiring harness and securing the wiring harness with zip ties.
