I can't seem to find the IAB/Secondary Butterfly (Pink/Blue wire). Is this wire located in the passenger side, or the driver side Engine Harness on a 97 B18C engine?

 

If the harness is off the car, the IAB has a grey plug. It will be on the same section as the knock sensor (green plug) and oil pressure switch. All of which are under the intake manifold on the drivers side. You could always plug up the harness at the shock tower and test the pin at the ecu for continuity. That way you know for sure.

The IAB wired on an OBDII engine are one black and one red with blue stripe wire. You can easily see it under the intake manifold from the driver side.

 

is it on the passenger side or the driver side?

 

Look fron the driver side. It's right under the intake manifold. There will be a plug with 2 wires, one is black/yellow, the other is red/blue<--IAB wire.
