1989 RX-7 ECU / O2 sensor portion

What part on the ECU is the O2 sensor connected to? There are just to many topics with these combined to find what I was looking for (I remember something about 12-pin connector? but that doesn't seem right).

Have you looked at the shop manual?

According to it, the O2 sensor is on plug 2, pin C.

In the FSM, it's either page F1-79, or F2-77, depending on non-turbo or trubo, respectively. These are the numbers in my 1991 manual.
