I've installed a 2010 Ram 2500 5.7 into a 1980 D100. I have everything from c130 to the pcm . I am using the A833OD trans so c4 should go away completely. I have the pinouts for C1, C2, C3,ALDL,Throttle Pedal and C130. I see the B+, Fuel Pump Relay power, and groungs but the is one lead for: Ignition Run/Start and one lead for: Ignition Off/Run/Start. Which one do I use?
Run/start. The other should be for power to the transmission you aren’t using
