It is wired like the pic. I think it is actually my battery, the old alt drained it pretty bad in a week, if you drive for awhile the volts actuall come down to 14.6.

 

For anyone wanting to know.........



From s4 to 91 na alt is....\



b/w wire trim back tape to harness

w/bl wiresnds to go on the terminal closest to the drivers side.

Run a new 12 ga wire from the other post to the pos terminal on the battery.



I took it down to the local alt shop, they put this gauge on it said is was putting out close to 120 amp at 14.1 volts hooked up like it was.
