if you dont mind could you go over the steps. I looked over the TIS link you provided and it helps but its not clear to me.
Would I need to release the sliver connector then pull off with my hand, then use a wrench that will fit and remove the oil pressure switch. Once removed replace with new one and tighten. lastly connect the plug and reconnect the silver connector?
Over all can this be done without removing any items surrounding and basically use hand to squeeze in?
