is this the radiator fan connector (red & green plug)? it has a brown/black wire and a black wire running into it. it was capped and not in use. the two white plugs are the wiring kit included with the radiator fan. or is the actual plug really up under the gas tank and i have to take it off? i searched around with a light and didn't see any free plugs floating around under the gas tank areas i could see into.
