Picked up a new to me 05 Mack Granite with an E7
Both the Mack is new to me, and I am new to Mack. Got a good deal on it.
Was kind of surprised that there wasn't a switch for manually turning on the engine fan, of if there is one it's hiding somewhere and I don't recognize it.
Running in the Rocky Mountains this won't do. Anybody able to help me out on how to run a switch to bypass the ecm and turn the fan on manually?
