S300 w/ MAC boost solenoid wiring help

I have 2 questions:
1.) The Hondata instructions say to use pin A11, but the EVAP purge solenoid is wired to pin A20 on my '95 Integra GS-R. Shouldn't I be using pin A20?

2.) On my OBD-1 GS-R engine wire harness, would it be okay to wire straight into the EVAP purge solenoid's 2-pin connector to power the boost control solenoid? The ylw/blk wire is switched 12VDC+ and the other wire goes to ECU pin A20. Any reason why I can't use the existing wiring to power the solenoid?

Thanks

You do not use EVAP purge to run boost control. Follow the instructions in the software as they are correct. It must be connected to A11 as it says.
