Hey all. I've just gotten my first car, and recently had it diagnosed, and one of the issues is my oil pressure switch has gone out. The dealer wants to charge me 171, but the part is only around 20 bucks and from what I hear it's not that difficult a job, so I'd like to take a crack at it.

Could somebody please point me in the right direction on how to do this job? Pictures, diagrams, and any advice would be greatly appreciated!
