Hi tripingeorge,
Have a read here: http://wbo2.com/cable/connkit.htm , with regards to the "Bosch CNK17025 Connector (for LSU 4.9)" chapter and the 17025 mating connector picture on the right side.
Red = Ip
Yellow = Vs/Ip
Black = Vs
Grey = Heater +
White = Heater -
By the way: which 928 and MY do you have, and why the wideband o2 (just for measuring, or SC install or..)?

just for meauring. thats the problem. my gauge has one wire for signal input. i understand the heater + and -, but don't know what to do with the other 3. what is Ip, Vs/IP and Vs. how and to what do i connect those to. there is nowhere for those to go on my gauge. so do i connect 12v to those and one is signal?? can't find any info. my gauge has a negative and signal wire input
