Unfortunate this was not answered before. Would have helped greatly. Going to break out the multimeter I suppose.

Anyone know which one is ACC? I'll be sure to update should I find one.

Edit: LOL found it on the first shot... and then the very next link on google turned up the confirmation on here as well.

For anyone else looking for this info... go here: http://www.xoutpost.com/bmw-sav-foru...e-bay-box.html
