Step Three
The picture below shows one set of male and female connectors on the Full Flex. Take all sets and pull them through the engine compartment and bring them close to each injector. It's easier to pull the connectors through the engine compartment that it is the pull the Full Flex computer. So find a good mounting spot and then fish your wires. .

Step Four
Now we plug the connector on the fuel injector and the other
connector will plug into the fuel injection wiring harness.
Note- Since firing order is still controlled by the ECM,
it does not matter which set of conversion kit connectors
you install on a specific injector.

Step Six
Double check that all of the are plugged snuggly. Mount the FFI Platinum with self-tapping screws, double sided tape or zip ties. Also make sure that the FFI Platinum's cables are not touching any hot surfaces. Use ample zip ties to make sure the wires wont move over time.

Your FFI Platinum is installed! Start your engine and
make sure that it is running smoothly and
the check engine light remains off.
 
Step Seven
Upon completion of the installation, drive for about ten miles. If your vehicle is running smoothly and the check engine light remains off, then head to your E85 Station. Fill up the vehicle with 50% of gasoline and 50% of E85. This will allow the system to create a map of the burning process. Your next tank should be all E85. Subsequent fill ups can be any combination of gas or ethanol.
