Ok guys my first posrt here. Any mistakes i apologize for in advance .Im hooking up a different harness than i had and i need to know what wires need to be hooked up. The red is ignition i believe the yellow is the charging light and the whit im not sure .If anyone can tell me what each of these is you can save me another replacement of my main alternator 120 fuse. Thanks in advance! The original alternator had a two pronged harness so obviously it only had 2 currents the one i am hooking up now has 3 prongs but only 2 wires. So to help you understand what im saying is this .I have three wires to hook up to two wires on the harness and alternator that is now in the car. Thank you .
