(The 2nd & 3rd being "digit zero," not "letter O.") That number is not easy to come by -- make a note of it if you have the relevant alternator.

As of this writing, Pelican sells it for $65 but it doesn't cross-reference to the E46 and you won't find it on their site. You must call with the Bosch number above.

I should have paid more attention to this thread. Got mine off without removing the alternator, put the new one on before realizing it was a different plug. The old one is back on for now, and I will call Pelican on Monday. The hardest part was getting the screws out.
