Dad is looking at me incredulously now for three reasons.
A: it's too easy to get to. People want $1000 to replace it, so he expects to take the car halfway apart to get to the problem.
B: All the "computers" he's been shown at the parts house either had two connections or four. This one has three..
and
C: he was told that this is the airbag control module.
