i swap a 98 d16y8 M/T on my 97 civic dx M/T. i put a 98 d16y8 engine, transmission, wiring harness and p2p ecu. my problem is it doesnt have a iac valve, so my iac plug from the harness have nothing to plug on to. any suggestions how to fix it? can i just use the throttle body from my d16y7, change the throttle rotor to match the d16y8 and take the iac plug (3 wire) from the my d16y7 harness and replace the iac plug(2 wire) on my d16y8 harness? which wires should i attach?
any help will be highly appreciated.

thanks

 

Purchase an IACV that bolts onto the manifold.

You do have a spot for it on the manifold, correct?

 

Go to the junk yard and pull an iacv and bolt it onto the back of your y8, problem solved. Don't do the y7 throttle conversion, not worth your time. Just do it right the first time it will save you headaches in the long run.
