[Hot Air]

Ready to connect my GM Flex Fuel sensor to FAST and haven't a clue where I might find this connection! HELP!!!

You will have to hard wire it into the box.

That is what I had assumed but, after looking at the pinout for the box (see link below), I don't see the shaft connector listed. HELP!! Appears to me it is part of the FAST VSS & Aux Shaft Harness kit (part # 30-1403) but connot find a photo of this or any indication of where it is located.....under the dash??

It seems as tho they use the shaft inputs to run the xfi, if that's the case pins A2 A6 A13 A17 will have to be used. Obviously Cal would be the guy to consult about this.

According to an old communication with Kevin Winstead with FAST, GM sensor is connected as follows:
"Flex Fuel sensor Pin A signal foes to Pin B of XFI shaft connector
Flex Fuel sensor Pin B signal goes to 12v switched power supply
Flex Fuel sensor Pin C sensor ground goes to Pin C of the SFI shaft"!

That is 3 wires...not 4????

Makes sense.

If your XFI utilizes the Casper box and wiring, your wiring harness does NOT have a Shaft connection! I talked with Kevin Win stead with FAST...he has several TR's....one has Casper XFI setup and one has FAST harness that DOES NOT use Casper box! Hell, I didn't such a thing existed.

Conrad, I ran my flex sensor (2012 GM Flex sensor) signal wire to A6, 12v to ignition on power, and ground to ground.....

Seems to work. My fuel constant went from .680 to .698 on XFI
