MAC-14 Diagnostics

I’m trying to run codes on my MAC-14 ECU which is currently setup to do only ignition
for my Megasquirt setup.  The wiring harness has been completely transplanted, and I
installed connectors for the “dirty” OBD to connect to VAG-COM.  VAG-COM is not picking
up on it.

Has anyone retrieved codes via VAG-COM for the MAC-14?

I will try connecting to flash the codes, but would be nice to use the OBD features.
Anyone had much success flashing the codes using fuse and CEL?  I don’t have identical
wiring with Fuel Pump Relay, but have wired according to Bentley.  Wondering if I am
missing anything for this.
