Anyone own a flex fuel ranger? Interesting favor to ask...

[Buggyman]

I am currently stuck and frustrated with my engine swap...

I am trying to put a 2000 flex fuel motor into my 1998 ranger body. Everything has gone well and it will start and run on my 98' ECU, but its rough and runs rich. I bought a 00' flex fuel ECU today on Ebay but now I am trying to figure out where the flex fuel sensor plugs into the wiring....

I bought the 2000 motor with a chassis, body removed. It has the 2000 fuel system with the fuel tank, pump, fuel plumbing and flex fuel sensor, but the wiring to the sensor has been REMOVED. When I had the motor out, I could not find any wiring on the motor its self that did not have a destination, thus I believe that the wiring to the sensor must have gone into the wiring for the body that tied back into the ECU in the junction box on top of the intake.

I have searched and searched and can find NO information at all about the wiring for the flex sensor, even my shop manual for the 2000 ranger did not mention it, the only thing it had was a listing for a "octane adjustment" sensor, but it showed it only having two wires, this one has three.

Heres the favor I am asking for someone who might be willing to do this. I was wondering if you could craw under your truck and take a peak at your flex fuel sensor and tell me what color wires it has running to it? I am hoping I can pull my ECU harness open and find the same color wires and tap into that and make my own harness to run to my sensor. If you could get a picture, it would be even better, but just knowing what color code the wires are will help a lot.

Hope this is not asking for too much and thanks for any help.

Do you still have your 98 engine? If you do, pull the fuel injectors and put in the 2000 FFV, and use your 98 PCM. The FFV fuel injectors have a higher flow rate.

The wiring I have on my truck is:
green (maybe dark green) with light green stripe
gray (also maybe dark gray) with orange stripe
black

My Haynes book says the one is dark green and the other is just gray.

They run from the FF sensor back to a Y-ish connector, then the main harness from that runs up into the floor of the cab (roughly under the drivers seat.

I took a couple of pictures while I was checking it out, so if you would like me to post them let me know.
