1) B+ goes to the Batt pos. (alternator small screw post with nut/washer).
2) Grey/Red: alternator light feed. This goes onto my Bosch where it says D+. Just crimp on a female spade terminal plug to this wire and push it on.
That should be all you need to get running.
**Make sure you disconnect the batt neg lead before fitting the B+ wire. If it touches the alternator body it can cause excessive current to blow the diodes inside the alternator.
Other ones may not be necessary.............
Yellow/Grey: Thats for an electronic choke. Just tape it up and don't use it....unless you have one.
Blue: normally for the horn?? So not sure what that ones for if its on your alternator.
i had pretty much just got to this point also. the Yellow/Grey is for old choke.
the blue or violet? is the only one i am stuck on... and yes i cant see anywhere on the old alternator where it went?
so with the new bosch, they giv you the new plug to use, it has L and S. One is for charge dash light and one for charger indicator or something. I know the Grey/Red goes to the dsh, do i leave the other with nothing? willl it know to charge?
