I'll check my box of them at home. I think I have one out of an 88 mark vii in there, is that the right one?

I don't know. I'm confused honestly... I don't know the significance of the A9L... I know they are used for mass air conversions, but why not any of the other computers? I'm running a chip, so I'm not sure if it completely overrides the A9L's programming or just supplements it. And would my chip /tune work with other mass air computers? If so, which ones? Mark Vii? T-Bird? I see 7 different computers used for 88-93 5.0 mustangs with manual transmissions... Will all of those work?

I'm lost.

I also need an A9L for my mass air conversion... I think the a9l is specific to a five speed

I found this:
There is a hardware difference between an auto processor & a manual processor. The difference is because of the way the NDS [neutral drive switch, manual trans] & the NSS [neutral safety switch, auto trans] are wired. They are both wired to the same pin#30 but the auto trans wiring grounds the pin to the starter solenoid & the manual grounds to signal return, during crank mode there is a voltage spike sent to pin-30 so the auto trans processor has a diode on pin 30 where as the manual processor doesn't, most of the time this won't cause a problem unless you get into a prolonged crank condition. Long cranking can burn the "signal return" (pin #46) trace in a manual trans EEC.

I've been warning people about converting an auto to a manual and using the manual EEC with the auto wiring harness; those that want to convert their automatics to manuals, and swap the ECM, need to clip the wire going to pin 30 or else the ECM could fry the trace.

You should try finding parts for an 87 Turbo Buick.

When mine died i used the dead one as a core at O'reillys. It cost me $100

Tried that but they didn't say A9L on it... Had A3M or something along those lines.
