Help! TII Wiring experts! Confused about O2 and Knock sensor diagram.
I'm trying to help my buddy find the O2 sensor wire which seems non-existent in his TII as well as his spare TII wiring harness.
All we see is the knock sensor wire, Black in colour, coming out near the area of the rear housing. Looking at the wiring diagram, the wires for the knock and oxygen sensor are supposed to be Green w/Yellow stripe, and are apparently shielded to ground. At the computer, the wire is indeed this colour, going to the 2D pin at the computer. I'm also not sure whether the two sensor wires are supposed to be connected, although the multimeter is telling me that they are, when connecting the O2 pin at the computer to the knock sensor wire.
We've rebuilt about four or five engines together, I've resolderered and fixed CPU's, a logicon, warning lights, solved numerous electrical problems and disassembled RX-7's right down to the frame. I thought I knew something about these cars by now...but my experience is mostly on NA's

The colour given for the knock sensor and oxygen sensor wires is misleading anyway, as this is the colour of the shielded part of the wire, which is inside the harness. At each end of the wire the shielded part stops and the black inner wire is what's visible. The oxygen sensor wire comes out of the harness at the same place as the BAC valve wires.
I'm also not sure whether the two sensor wires are supposed to be connected, although the multimeter is telling me that they are, when connecting the O2 pin at the computer to the knock sensor wire.
