What is this??
Upon taking out my computer today, I saw that there was this box dangling around. It had the letters AC on it from a company? I opened it up and it was a big relay(?) board. It was plugged up and HEre are some pics.

kowboy59: Looks to be the cruise control module. See if the cruise still works with it unplugged.
Cambridge205: yellow box, most likely the VSS buffer box. Should have a paper label on it stating "4 out buffer."
