Yeah I'm confused. You came by the shop and we plugged in an obd1 working ls dizzy. But you have an obd0 ecu? I guess the question is do you just need a jumper harness, or did the previous owner wire up an obd1 dist. and obd1 plugs....... Your best bet might be to find an obd0 dist. and make the car back to stock with the correct engine harness plugs.
