no start
 

2000 cherokee 4.0
I have replaced the engine and now get the no bus code on dash.
I have 2 black wires with orange line on the and round ends as if they were a ground but they have positive feed. The wires are on the passenger side engine bay and run tward the alternator I do not know where thease 2 wires belong! Im hoping this is my problem
I replaced cps
replaced ecm( brand new 600$)
And have been digging threw my wiring hrness for hours looking for a possible problem...

Not to sure what those wires are... Have you looked at a wiring diagram?
