Last year I swapped a Buick V6 into my 914. For the time being I got away using the original 914 Bosch alternator. Now that I found a high quality mount for a GM alternator (Thanks Paul!) I am replacing the original Bosch alternator since I know it won't last with out cooling air to it.
I did a search here and found Scott's (Skline) illustration/schematic how to wire it. I read and reread the Haynes manual wiring diagram and as best I can tell there should be a blue wire coming off the alternator warning light and it appears that the blue wire terminates at the relay box pin number 2 which connects to the D+ plug-in of the original voltage regulator. With the GM alternator the original voltage regulated isn't needed. Can anyone confirm that it is the blue wire that goes to the alternator warning light and terminates at the D+ plug? I need to know if that's where I should connect the other wire of the GM alternator to so my alternator warning light will continue to function.
