Default 97 Caddy STS - Ground Locations

Does anyone have a resource that they could find out where the grounds for the PCM and heated O2 sensors are?

They are G102/G203 for the PCM and G109 for the O2 sensors. I need to know the approximate locations of these grounds. Also, if you can find out what Ground Distribution Cell 14 is referring to, that would be great as well.

My parents STS is having issues with a slow heat on all 4 of the O2 sensors and they all have been replaced. The connectors get good voltage (+), but the ground condition doesn't seem right. I wanted to clean up the grounds for the PCM and O2 sensors to get that out of the way before I start un-looming the harness to look for frayed wires.
