Default GSR IAB Wiring Question

I'm currently swapping in a JDM B18C GSR engine with a P72 ECU into my 1995 integra that originally came with a B18B. I have almost everything done but now that I'm finishing up the wiring I ran into a problem with the IAB wiring. I'm using two different diagrams that both say one of the IAB wires goes into the pin location of A20. The problem is I already have a pin in the A20 location for the EVAP purge Solenoid. I'm not sure if I should splice into the existing wire or remove it and relocate it, and if so where? I don't want to start the car and have something wired wrong so any help would be greatly appreciated.

For reference these are the diagrams I'm using

Both of those seem to reference A17 for IAB...

The light purple dot in the last picture is marked incorrectly... A20 is actually a controlled ground that operates the EVAP/Purge system. The second wire in the two pin connector at the EVAP/Purge valve is actually the 12v+ wire... which is essentially a switched 12V+ signal. The two pin connector at the IAB solenoid also uses a 12v+ switched wire... and the other wire is the controlled ground from the ECU at A17.

Thanks guys that clears it up. I already have one wire in the A17 pin so it looks like I just need to splice the other wire to a yellow/black 12v+ wire.

Unless you are me, and you do that, and IAB still doesn't work!
