So while my car is down and the engine is out I thought I might as well hook up my flex sensor to the return line and wire it up. I was thinking around the same are that SOS mounts theres, but how do I wire it up. I have a MY07 so my AEM V2 plugs into my stock ecu. I don't have the Zentronix gauge but I do have the Digital Logic mounted to my AEM V2 to out to my iphone5. Can I have the E85 gauge show up on it? Lastly is there a connector I need to get to plug it into the aem or do I splice it in? Thank you.

 

Did you buy the GM flex fuel sensor? There is a cheap GM harness that we all bought that has the plug that connects to the sensor. We all just cut off the plug on the other end, extend the wires, and wire the signal wire into an input on the ECU.

Good info in this thread, specifically on page 3 concerning wiring it up: https://www.s2ki.com/s2000/topic/108...exfuel-sensor/

 

Yes the GM sensor with the harness is the one I have. Thanks.

 

By popular request, we've made our FlexFuel kit available separately with out the sensor for customers who already purchased one. This includes the stainless mounting bracket and hardware, all required fittings, and the electrical kit (so you don't need to hack up the GM harness or buy one separately), along with our awesome instructions.
