Hey guys,
Just trying to figure out the wiring for this. It's a '99 B20 swap into a '96 Civic CX.
Thanks!

Are you using the stock CX harness that has a 3 wire IACV plug and need to change to a 2 wire IACV plug? If so, you'll need to obviously change the plug to a standard round 2 prong plug.
At the ECU you need to move the wire at A14 to A12. Then unpin A13 and leave it unpinned, you can tape or ziptie the wire back out the way if you want, it's useless.
Under the hood you will unpin the BLK/BLU (goes to A12) and the GRN/BLK (12V+ switched power) on the stock CX IACV plug. These are the 2 wires you will connect to the new 2 wire IACV plug. You will disregard the ORG wire which went to the wire you unpinned at A13.

Yup, I knew about leaving the OJ wire unhooked at the IACV but I was unsure about what to do at the ecu side. Thanks very much!
