Flex Fuel Sensor Wiring

So I think I am lost. I am pretty sure the flex fuel sensor that is inline on the fuel lines needs to be hooked up to the ecu, but I can't find a connector in my engine harness, and I also can't find any reference to it in the XLS files for all the wiring on the C100, C152, C153 pin outs for my 2005 engine. Anyone wired this up already? I am sure it has to go back to the ecu somehow.

Thanks in advance!

usually the connector is on the drivers side of harness, extends past the transmission connector, before the harness jumps over the transmission. Usually right next to rear oxygen sensor connector (may have been removed from you're harness) its 3 pins, Pink, Black, White. Same type of plug as the map sensor, crank sensor, cam sensor..

I think the sensor was only used until 2005. After that the pcm, fuel level, and o2 sensor calculate how much alky is in the tank.

Busta9876/Fast400,

Thanks. This is an 05, and the sensor came with it from the junk yard. I will go over my harness again, worst case I would guess they just cut off the connector, which I can replace. I was just worried that it was on the body harness or something dumb like that.
