I replaced the Oil Sensing (sending??) unit. I didn't know what the oil pressure switch was until you told me. The wires at the switch had been spliced together to bypass the switch ever since I bought the boat and has been running like that for eleven years.

I looked for one just like the one on the boat (pic attached). I didn't see one like it on the Napa site but I guess it doesn't have to look the same (???). I should just change the wire connectors to fit over the one post??

In another post R98ROO said something about a violet wire running to a kill switch. Do you know what and where that is?
