Krazy-K

Hay im a newb!!!!!! But I did spend 10 years in a dealer as a tech, I. E. not stupid.... I reacently got an 88 lx 5.0. I am converting to mass air. I did get a A9l \comp. But the car came with a A9e NOT installed. My question is is the a9e a mass air comp???? I was un sure so I located a A9l for my car. If the A9e is a mass air comp it is going to be for sale. I really dont want to miss represent what this module is. I cannot locate its use. I was told it came out of a MERC. but im unsure. Any one know????????
