Does anyone know what car this alternator came off of

I have an alternator that is on a 1983 RX7 Lemons car and it is not a stock alternator according to the auto parts store. They tried to test it for me and it did not have the proper connectors. I understand there is some popular upgrades for the RX7s and hoping one of you will recognize what i have and help me out so it can be tested.

Looks like a Series 4 ('86-88) alternator. Might be a late Series 3, been a while since I have seen one.

Subarus with V-belt pullies bolt right up and plug in, you just need to use an 8mm through bolt instead of the 10mm one. The funny thing is, Mazdas had Mitsubishi electronics and Subarus had Hitachi electronics, but the alternators made by different companies had the exact same form factors and connectors, almost like there was a JIS standard for alternators.
(On my '80, the alternator died, and I had the alternator from my previous car, an '88 Subaru GL, and I was like, hmm, I am broke and this might work... Probably impossible to find an EA82 engined Subaru in a junkyard, but the EJ22/25 engines look like they still use the same form factor, just need to swap pullies and connectors, maybe add a diode like you have to do when you use an '89-91 RX-7 alternator)
