Refer to the AEM manual for the proper pins for your year, but on my 88 I used the PNP pin for the AIT, which is 8C, and pin 2-5 which is default for the MAP.
Again, refer to the AEM manual and it will show you which pins are which, and how to go through and set up each sensor (for example if you have a 2 bar map or a 3 bar map).
