Which o2 sensors do you use?

I hope that diagram isn't too much different than mine. I have a 93 computer/engine and the label says 88-91...

The computers are interchangeable 88(maf)-93, so the pinout can't really be any different. Not sure why it says that, maybe the wire colors changed or something.

The thing under the passenger seat is the factory amp. The 6-speaker "premium" sound system comes with that amp.
