NEED HELP TO IDENTFY THIS SENSOR AND WHERE DOES THE WIRE CONNECT TO...PLEASE.

Can anyone could tell me what is this sensor and where does the wires connect to....it got a black wire which i believed is ground-wire....and the white wire....now, where do i connect that one to? i am doing the rb20det automatic. Also, on the 8-wires plug i tracked 3 of the wires(A/T control input signal) the pink-wire(pin#5), the red-wire(pin#15) and the yelllow/red(pin#56). Now, if i don't use the 8-wires plug then don't i suppose to re-connect those wires to the KA lower harness plug?

um iirc its for the fuel pump but the car will run just fine without it, last time i traced it the wire went nowhere.

Wussup Carl. Darnmit!!!! all this time i wired it to the RB20 pin#40 which i don't even know what pin#40 is for beside it's white wire. I check the rb20det ecu diagram and it doesn't even had pin#40 only pin#38 which is for throttle opening output and i check my automatic ecu and it doesn't had pin #38. Just got the new ecu yesterday and i hook it up and tried to crank it but the car still won't fired up. and so i pull the harness back out and trying to trace back all the wiring. If it still won't fired up then you know what!!!!! I will sent it to you.

Oh, my bad, i mean on the automatic ecu it had pin #40(white wire) but on the manual rb20det ecu diagram it doesn't had pin #40. and yes, automatic ecu rb20 does had pin #38. does anyone know what pin #40 is for on the rb20det auto ecu?

#40 = intake air quantity output signal
