the only things I can find sticking out of my cylinder head top are a blue sensor with green and brown wires and a green sensor with black/green and pink/green
wires (it's hard to tell if it's black/green or black/yellow and pink/green or pink/yellow)...and a black sensor with one black wire. None with 3 wires. When my a/c was working the fans worked fine...but it's locked up now and I just want to be safe and know they will still come on because they aren't running now without the ac.
