alternator swap from bosch single wire to Denso four conductor connector R1200gsa bmw

[petergsa]

The title is the basic message, The Denso alternator has the four pin connector, where as my 2006 gsa has a bosch single connector going to the engine management computer, just guessing here. any ideas on which one of the four pins should be my contact point on the Denso unit I could use to make the Denso unit operate as the bosch unit did with the single wire connector .
Thank you
Peter.

I did this conversion but in reverse, you should be able to get a conversion cable from Motorworks and I’m sure they will tell you what goes were.
