Alright so after I removed most of my ac I went to its wiring harness to remove what I could , stripped down the looming to see where the wires went, and here's what I found; there are two plugs on my radiator shroud ; one green one a yellowish clear, the green one has a black wire which splices into one of the ac harnesses relays sharing a common ground, another wire from the yellowish clear plug that also goes into a relay on the ac harness , I know the green plug goes to my radiator fan but what is the job of this yellowish clear plug??
