Re: WHERE DOES BLUE WIRE FOR VAFC 1 GO TO ON ECU? (boosted1993)
it's just that the VTM wire on the Apex VAFC original instructions was not spliced to the ECU pin for the Integra GSR/ITR. It was originally not connected to anything on the ECU and left to dangle on it's own.
on an updated set of instructions, Apex later recommended splicing the VTM wire on the VAFC's harness to a specific ECU pin out..btw, it's C15 = vtec solenoid oil pressure sensor, blue wire on your wiring harness). They found this out after they released the product in the late 90's after users like me badgered their tech line in California by long distance that the VTEC wouldn't work unless you did this. People were throwing CEL 22 codes left and right after VAFC installs and didn't know why, back in the day.
VTM Wire goes to ECU Pin C15, you must splice into the wire...
