hello, I have a 92 honda prelude with a f22a1 engine, I'm turboing the car, I'm installing the S-AFC. I got all the wires hooked up, but when I look to hook up the pressure signal, its not there in the ECU. its an empty pin on the plastic block. It should be the yellow and white wire on the AFC. I'm using the H2-a ECU wiring diagram in the apexi book. Do i need the pressure signal, please help, ,thanks ray

 

Im not completly sure about yours, but I hooked up a vafc on my h22a4 and the pressure wire came loose, and the car ran like ****, (backfired and smoked a ton) I actually went through an entire tank of gas in 1 hour. Once I hooked the pressure wire back in, everything was perfect.
