Plug ID And wiring C100

Looking for help identifying the plug in the attached picture, this plug is tied into the wiper motor. Also, do i need all three wires for the oil sender it's tied into another plug? And if there are any other wires that I could get rid of on the table picture. I am using a vintage air system so I do not need any thing for the blower and A/C
Thanks Rich

Re: Plug ID And wiring C100

I figured out the plug with the yellow wire, it goes to the bottom of my wiper motor. I need help with the oil sender plug, I believe one of the tan and orange wire went to a fuse plug and relay for a fuel pump safety cut off. What wire and location is needed to make my V6 oil sensor work. I have this sensor in my LS1 with an adapter
Thanks Rich.
