Make sure you get the one that say w/guage or it won't work in the Bonnie. The other one is for the Grand Prix which don't have guages, just the dummy light.

Found 2 part numbers in here. Which one is correct for 2000-2005 Bonneville.
1. 12584940
2. 12574309

It is GM part number 12584940 for the w/gauge
It is GM part number 12574309 w/o a gauge (only the dummy light)

2000+ have a gauge and the second one will not work with it.
