that's what I needed to know. The newer alternators have a internally voltage regulator and are controled by a cpu, right? My 87 Dakota uses the external regulator. So, as I am starting up the engine, I am beginning to think that the wiring on the "new" (that is, the 99 alternator) won't work with the old style "external" regulator. So, you say the blue is ignition, green is not used. You can't just cut those off completely. It has to run to the alternator some how to turn it off and on to keep the voltage going to the battery doesn't it. Does it have to have the cpu, or can I remove the internal regulator and keep the old setup? Anyway, do you see where I am going?
