S4 alternator back plug with haltech swap?
The wire going from the back of the ALT to the ECU is gone with my old harness.
Is the backplug&WIRE needed for the alternator to work and charge the battery?
If it is needed, how do I wire it?

hummmm k your right. The problem is that my car was a S4 N/A.
What is the real use of the alternator back switch? Is it used to regulate or to turn ON the alternator or its only for the idiot light?
