I have a 99 grand caravan and I am trying to replace the oil sending unit. In the process it seems that the little green plug attached to the old on got broken. My questions to you are how do I properly take this thing off, and where can I get a replacement part? It might be salvageable... just a piece of the plastic snapped off. Any help would be greatly appreciated.

 

Call the dealer and ask them if there is a replacement connector for the oil pressure switch.
