SEE BELOW FOR UPDATED QUESTION
I am attempting to correct the P0141 code and have read a bundle of IC posts. Renunergy's post with the GM guide to diagnosing O2 sensor malfunctions is intriguing and I would like to troubleshoot the downstream O2 sensor heater circuit.

Only trouble, my whatever make O2 sensor plug does not have the 'C' and 'D' connector designations that GM has, so I cannot distinguish the heater from the sensor poles. My plug has the 2x2 array of wires with two adjacent white wires, a gray and a black wire.
Anyone have insight experience with this?
