Another (No bus) Issue)

[JohnW]

I am the newbee here with the no buss situation. Today my van died and got the no bus in the odometer. I have the pcm on the fire wall with 3 plugs. When I wiggled the plug on the right I heard the pcm and fuel pump kick in meaning I had power. What I am looking for is a pcm pin out Chart/diagram to see what that plug does. I have a 1999 Dodge b1500 van. Thanks

Pin outs for all three plugs on the ECM for a 1999 Ram 1500 van 5.2 Not sure which one is the "one on the right" as the ECM could be mounted upside down... but they are color coded.

Black plug = C1
White plug = C2
Gray(Grey) plug C3
