Found this out, has the wire colors for bosh, and a few other brands of, aftermarket 02 sensors with 4 wires.

Black = Signal.
Gray = Ground.
White x2 = Heater.

Might be useful to some.

While I'm off work I wanna get these wired up, and I can't read a wiring diagram for shit.

I've found these here:

http://www.mx-3.com/manuals/showimg.php?file=/1995 Workshop Manual/Z/Z-032.gif

This reads to me that

Red\Blue (R\L)
Black\White (B\W)
Black (B)

Are the colors loom side and

Black = Signal.
Gray = Ground.
White x2 = Heater.

Are the details sensor side.

But which ones connect to which?
