Elite 1500 Flex Fuel wiring

So I'm getting ready to wire in my flex fuel sensor and I basically need to find a 0-5v input.
It looks like there are a total of 10 AVI's. I'm running a non-sequential setup with emissions still installed. I used a PNP harness adapter. Reading the wiring diagram, it looks like maybe 12, 13 or 20 on the 26 pin, or 2, 16, or 17 on the 34 pin are available?
I repurposed the MAP connection for my fuel pressure sensor (pin 15). I don't think there are any other inputs I can repurpose, but if there is, that would make my life easier.
It also looks like pin 9 is a single generic +5v supply to the sensors, can I just tap into this for the ff sensor?
Any insite would be helpful. This is kind of a sanity check before I start.

Flex fuel sensor requires switched 12v, signal ground and a SPI, not avi. The fuel pressure sensor you could run on a avi.

Thank you for that, I was way off. For some reason I was thinking it was 0-5v out... it literally shows it in the wiring diagram by the SPI connections.
Thanks again
