Ok, I'm strongly considering trying to swap the 96 EX ECU into my 96 DX since the IACV is giving me so much trouble. A quick glance at the Helms manual tells me these wires exist for the D16Y8 motor and not for my D16Y7:

D15 - PTANK
C15 - VTM, VTEC Pressure Switch
A8 - VTEC Solenoid Valve

So, I am using a Fields box for VTEC. Does this mean I can leave C15 and A8 unconnected, or will it throw a code?

Next, WTF is PTANK? I think it might be fuel tank pressure? I saw something in the Helms about fuel tank pressure for D16Y8 motors.

Last, of course, I will need to move one wire to make the IACV function properly. Anybody see anything I missed? Please help!

 

if you got the fields vtec controlling your vtec and pressure your fine. but the vtec must be connected to your vtec controller also the pressure. there will be at lease two to three wires (i think) that connects to your ecu. by that it will tell your ecu not to throw any codes.
