2JZ OEM O2 sensor wire colors

[crazysupra2JZ]

i've looked at the 95 TSRM many times and i can only match one wire for the OEM O2 sensor. the white one. the other colors are Black Red, Black orange(i believe)

i know i have the right plug cause i checked the white wire at the check connector. but on the diagram it shows more wires than i have.
i bought a bosch sensor. i hooked up the black wire to the white wire(signal)
and the white wires on the O2 are for the heater, that's what i can't find on the engine harness

at the o2 sensor
Pin 1 - BR-W (brown with stripe) is Heater Ground
Pin 2 - B-R (black, red stripe) is +12v
pin 3 - R-L (red blue stripe) is o2 signal
pin 4 - BR (Brown) is ground

Page 72 of the Diagrams pdf..

edit: oops those are Ox2

Ox1 is
Pin 1 - B-L (Black, Blue Stripe) is Heater Ground
Pin 2 - B-R (black, red stripe) is +12v
pin 3 - W (white) is o2 signal
pin 4 - BR (Brown) is ground
