So according to my book it should have the Bosch Mono Jetronic A2.2?
I assume that would need a different wiring plug?
Unless the plug has been changed which would seem like a lot of hard work then yours came originally with the Weber-Marelli IAW SPi which I posted the ECU pin outs for.
If you think it has been changed or want the other Bosch Pin outs let me know.
