Since tossing my OBC, I have been closely monitoring my 12 VDC draws on the car since I now only have 36 amps to work with. According to canion my single largest load was the vacuum pump. I decided to look up the recall information and replace the pump since this recall was never performed on my car. (part#4641a032, 150$ on ebay) I included the service bulletin and some pictures of the old vs new pump current draw. The old pump sucked up 26 amps while the new one draws about 14, or roughly half. I thought this was a neat data point to share.
Here is a link to the recall instructions and some pictures:
