The big ones are for rear window wiper/washer and fog lights. The smaller ones I’m not 100% but I think possibly for the heater control (blower motor power). The connectors look like they are for that, however the color of the wiring is weird. Does each connector have two wires or is it just a black/orange color scheme on one wire?
I thought blower motor wiring was white on early years and green on later years so that is also part of why I’m really not for sure what the wiring is for in your pic.
