This kit is designed and built for the gen 1 CRUZE. It give your car the power to switch between Gas and E85. Not only that if your E85 has a lower ethanol content it will read the % and adjust your tune accordingly. This kit comes pre wired for a 2009-2016 CRUZE. It will have the connections specific to your fuel system and come with the fuel line disconnect tool. The harness will also be prewired for your ECM. I have set this up so you can be as plug and play an en OEM part.
++++NOTE: you will need a tune to run a flex fuel sensor+++
++++Some years of the gen 1 CRUZES you may need upgraded fuel injectors.++++
