Diagnostic computer connector, where is it?

[CaffeineRacer]

So this really would only apply to 81-83 Avanti owners, but where the heck is the ALDL connector on these cars!?!!?! I've searched high and low under the dash and can't find it.

There is one thing I found under drive dash just to the left of the steering column, but it's only got 5 pins instead of 12 which I thought that all had (maybe I'm wrong). Anyone have any idea or even better actually connected an OBDI computer to their car.

I'm in the process of upgrading the ECMS in my car to a later 87-88 unit (pn 1228079) which is a little faster and I can use the ZZ4 performance chip I have which removes the EGR and ESC codes, but is still like to check any other codes that might pop up as well as check the sensors in realtime.

Jim, awesome information. That's exactly what the terminal on my car looks like. Thank you so much. Knowing that I wonder if the newer computer will work at all. Guess I'll find out.
