I have been searching and can not find a definitive way of how to properly wire in a 88 dodge omni voltage regulator. 2002 galant 4cyl. there is a black wire with red line red wire with white line and a black with a yellow line and a white with green line.. can someone please help me out about how i should go about wiring this thing up!

I have had alternator tested and it tested good so i suspect ecm not signaling alternator to produce voltage.

hopefully someone can help me out , thanks!
