do you have the fuse box in front of the drivers side strut tower? I was wrong about the post, that should go to + as Lee pointed out. Is it still the S4 alternator (kinda dinky looking mitsubishi alt)?

no fuse boxes in my car at all accept the one i put in. Yes, it has the mitsu tri-diamond logo on it.



I'm thinking the large stud goes to the battery and leave the other two alone, not connecting them at all. I know it has a built in regulator but i'm not sure how it works.

why not just connect it? is there really a problem running those two wires? one is a positive and one is a negative. im so not wasting my time ripping through the FSM to tell you what they do....just look it up yourself, its only TWO wires, hell im doing two full harnesses for different cars at the same time.

Why are you so angry all the time? If you are building these harnesses I'm sure you must know something without looking at a book about the altonators... Just saying a simple I have no idea or this is how you do it would do... but you my man, act like I owe you $5. I didnt do anything to you.



Anyhow after reading up a bit i learned that the two wires are usefull. One goes to the chassis ground and the other goes to the ignition switch. The altonator has a built in voltage regulator. If you dont use these wires the regulator never gets turned on causing the altonator not to charge.
