my EK civic has 3 wires, but the h22a has only 2 wires for the IACV. i currently have black/blue A9 connected to black/blue (iacv p) A12. i also got yellow/black connected to IGN "on." what do i do with the orange wire A13 (IACV N) from the OBD2 civic? the car starts and idles fine, but wont take acceleration well - it basically surges and misses.

well, what is the third wire used for in the OBD2 system then?

i still have a code 14. i just got a new IACV from steve at HMO too, so it should be good... im so frustrated i dont know what else to do... please help!

There exist 2 types of IACVs; 2 and 3 wire. They are not interchangeable nor can their respective ECU's control the opposite type.

The orange wire is left hanging when doing a 3-wire to 2-wire IACV swap.

to add...
check out the IACV notes in my diagram here:

thanks katman.... i cant read the first post cuz everythings so darn small. i was actually looking at the harness i bought from JDMshit and making sure they did the wiring correctly, and it looked to me like they fucked some **** up. ill be checking it out more tomorrow when i have time.

on a side note, i revved the engine up quite a bit and DAMN is that badass sounding (running open header).

It's probably because Internet Explorer is auto-resizing my image. Save my diagram to your desktop, then open it up with whatever image viewing program you have & zoom in. The text is totally readible...
