I thought you figured that out before you started the car.

Luckily for you, I have a 1994 Integra service manual handy and it shows the map sensor wire being White/Yellow and the pinout for that wire is D17. I don't know if that helps you any, but if you can find the same colored wire in the general vicinity of where it is on an OBD2 car, chances are that is the MAP sensor wire.
