Can anyone help me read a wiring diagram?

[03mustangdude]

Connector tore off an oxygen sensor and all i'm left with is 4 wires.

red black
yellow black
orange
pink/purple

I bought a universal bosch sensor

that has 2 white wires for the heater
1 black wire for the signal
1 ground wire that's optional but gray.

Attached is the wiring diagram.
since attachment is super small here is a zoomable link http://imgur.com/cuDtGVV
Which wires go where?

On that diagram, it looks like:
Red and Black (R/B )is Power (it goes to a 15A fuse).
Orange (O) is the signal that goes to the ECM (the O2 signal that the ECM reads)
Yellow and Black (B/Y) is Ground
Pink Purple (P/B) is the heater

Did you look at the other side for reference? Except for the signal wire, they should all be the same color, and orientation.
