o2 sensor wire colors

[sc1_of_a_kind]

long time reader first time poster, but heres my issue i bought the universal simulator from o2simulator.com and need to know what wire is what down there. ive read many threads here about it but couldnt find any that actually said what wires to use, i googled it nothing, checked the haynes repair manual but it only had info on a 2 wire sensor for up to 95's. and o2simulators website doesnt have any info for saturns.

so on a 99 sc1 which wire is the data wire to the ecu that gets cut, the purple or pink. and the 2 white wires are the power and ground that i use correct or should i use the sensor ground instead of the heater ground like o2simulator says to do.

any info is greatly appreciated

They changed the colors 97 to 98. However, ther are very small letters in the plug up on the rear cradle rail and this is what goes to the letters.

A- O2 sensor signal ground blk/wht
B- O2 return to PCM ppl/wht
C- Heater ground dk grn
D- Heater feed pnk

Those are the 98 colors.

According to the database I'm looking at, (appears to be sourced from a Chilton manual) for a 1999 the wires that come from elsewhere on the car and go to the female end of the downstream HO2S plug are....

A) BLK/WHT sensor data ground
B) PPL/WHT sensor data out to PCM
C) BLK/WHT heater circuit ground
D) PINK heater circuit +12v to UHJB EGR fuse

none of the wires are white in color, but three of them have a white stripe within another solid color
