Yes, I had previously used the brown wire that originally plugged into
the SI alternator. I had to extend the wires since the V6 had the alt
on the passenger side. I do not know where that brown wire
originates. I changed the "L" (lamp) exciter wire to a wire coming
from the HEI plug with a 470 ohm resistor.
I installed the new CS130 alternator and I'm back in business: 14.7
volts read at the alt. When the alternator is "on" with key turned
you can hear a high pitched sound, the same as the previous CS130
(before it died). I hope the resistance is correct...
One snag, I had to clock (rotate) the alternator housing so the stud
would clear the valve cover. I don't use the rear support, so this is
not a problem. It's a bit more tidy with the alternator plug hidden.
