If I recall from reading your other posts amongst some other threads, you said the previous owner installed some aftermarket audio equipment. This could be what is referred to as the Big 3. Its used to negate voltage drops that are caused by your aftermarket audio equipment when they are really sucking power. After some quick research, here is the 3 runs of wire you should have:

When doing this mod, 3 runs of wire will need to be installed. They are:

1. Battery positive (+) to alternator - From the positive terminal on your battery to the alternator positive (+) post
2. Engine block to chassis ground - From engine block to chasis. This is to strengthen the ground.
3. Battery ground (-) to chassis ground - From the negative terminal on your battery to your car's chassis.

I hope I'm not way off base here.
