Customer Question

Hi I am having trouble with a 2001 freighter classic 12.7 detroit. Check engine light comes on and when it does I lose throttle. the engine goes to idle. I know its the ecm harness because i can move wires at the ecm plug and make it work or make it not work. I need to know which wire control the throttle control.
