David Page with FAST gave the folllowing info to me today:
The GM Flex-Fuel Sensor PN is 12570260.
The wiring directions are, "The wiring is straight forward...power and ground to the sensor, signal to the XFI's Aux. (shaft) discrete input."
Conrad Carter
ps...This sensor is used by flex-fuel vehicles to tell the ECU which fuel is being burned. The GM list price is $612.20. You should be able to get it discounted to around $460. Ouch! It was available since 2000 in various GM vehicles. The list is included in other posts on the E85 Forum. Looks like some auto recycling yards will get a visit.
