So since I'm sitting on my rump at work bored I figure it's a good time to go over how I plumbed the flex fuel sensor.
First thing first. Parts list with some breakdown on price.
13507128 ACDelco/Continental flex sensor. Musta been a flash sale because they are around $50 now but I got it for $38 on Prime.
Vibrant 12275 pinch clamps $8.50 but only need 2 total for this.
8 pin connector 90980-10896 with pins that will plug into the stock AC2 harness connector was $20.90 and the only item I'm waiting to receive.
Boost Monkey flex fuel pigtail for $13.13. This means I only have to crimp 3 pins to the AC2 plug.
Gates 27335 5/16" fuel line. I bought 10' for $19.80 through Rockauto but maybe used a foot at best?
Dorman quick connects 800091 and 800085 for under $3 each. Also purchased through Rockauto. I only needed one 90 degree fitting and one of the straights so you will have a leftover.
Maxwell Manufacturing flex fuel billet mount for $28 on ebay.
Combined with the Kpower fuel supply line this is really all that's needed.
I took a spare bracket that was used for the stock intake box and flattened a spot for it to be bolted to the strut tower brace bolt. The Maxwell bracket bolted to it, and the lines point perfectly to the connectors. Into the sensor from the stock fuel hard line is a fuel clamped 5/16" hose feeding a 90 degree Dorman quick release clamped with the Vibrant crimp ring. Then a straight Dorman fitting crimped to the provided Kpower line which has a quick connect to their fuel rail. The Boost Monkey pigtail will pin to the AC2 plug and the rest is all settings to configure in the Haltech.

We've already made the provisions to run a flex fuel sensor quickly and easily. The Flex Fuel sensor signal is run off connector B, pin 8 on the Haltech ECU. All you need to do is go into the main setup on the ESP software, and set the Flex Fuel Composition Input to pin B8 (SPI1). From there, you'll have to set up the edge and sensor type according to which sensor you have. Once you have that setup, the rest is easy. Find the 8 pin connector (AC2) that runs right next to the main 54 pin connector that you'll plug the engine harness into. Everything you need is in the 8 pin connector. On that 8 pin connector, the 3 wires you'll need are as follows:
Pin 1 (light green/red stripe): 12V power
Pin 2 (white): Ground
Pin 3 (red/ green stripe): flex fuel sensor signal
