I’m a newb when it comes to CIS and 911’s. I am building a 79 930 that I purchased as a rolling chassis. I then purchased an 86 3.3 turbo engine with harness and jetronic box. I can’t find any reminents of such a control unit on the 79 chassis. So my questions are

1) what does the jetronic ECU control? Is it just 02 sensor?

2) does the ECU get its power from the engine? What all needs happen Ike’s up to make it run?

3) Can you identify the connectors in the pic marked with an arrow and tell me what their function is?

Thanks for your help. I’m pulling out my already rapidly decreasing hair. I’ll include a pic of the unit and wiring for reference
