I was wondering why the name sounded familiar. Decided to give up on the harness swap huh? You shouldn't have any issue with the parts you listed bolting to the B18A and allowing you to run a B18B OBD I ECU. I haven't tried it myself but I imagine it working. Are you still using the B18A cable tranny?
