1980 911SC O2 Control Box


Vehicle Information: Model: 911; Year: 1980; Body Type: Targa; Total Mileage: 155K;

Under the passengers seat is a control box with 10 leads. One is to the oxygen sensor. What are the others to? Also right next to that is a relay with 5 leads. What do these control and how do I check to see if it is working or not?
