Harness triming questions

[RO86SS]

OK here is what I got.86 Monte ss 350 Edelbrock intake and Edelbrock carb,hedman headers very basic and I'm planning to run a/c.OK to start off there is no ecm anymore.OK now i'm talking in reference to the harness that comes off the fuse block that goes to the alt,oil PSi gauge etc etc.my first question do I need the oil PSi sender conector that has at total of 4 wires going into it since I don't have the ecm anymore.I am going to use the 1 tan wire conector for my oil PSi gauge.but I'm not sure about the 4 wire connector
