Notice the markings on the ECU; they read xxx-p72-xxx, which is the appropriate ECU for a B18c swap. Since the civic already had vtec, the only wires that needed to be added were at D3 for the knock sensor and A17 for IAB. The pinout for the IAB can be switched from A20.

CAN SOMEBODY PLEASE EXPLAIN THIS TO ME IM STUCK....WHAT IS A "IAB" AND DO I EVEN NEED TO WORRY ABOUT IT...

AND WHERE IS THE NOCK SENSOR ON THE GSR DO I NEED TO WORRY ABOUT IT SINCE IM GOING OBD-1???

 

IAB are the butterflies on the manifold. If you look under the manifold youll see a little vac box with a connector.

KS is on the back of the block. Yes you need it if your going to run a p72.

 

how do i wire all that up to a 92 civic

 

and what does it mean switched from A20

 

You take the wire going to pin A20 and re rout it to pin A17.
