Pin D11? For AC input?
Hey guys!
I'm in the process of wiring my cooling fan system up, but I've got a question about the ECM wiring. As it stands, I have a large cooling fan that is wired so when the ECM provides ground, it activates the large fan, and I have the little fan set up so it recieves power when the fan switch in the head closes, acting as a back up fan.
I was just wondering however, if D11 is used as an AC input to tell the ECM to turn on the big fan?
My truck doesn't have AC, so I'm not concerned with it if it does, however, I would like to know, so I am not leaving something unhooked that needs to be hooked up, lol
