Hello! I am installing my third party AMP, with the stock AMP and subs in to my e46 today and was wondering if someone could confirm the wire colors that I tap the positive and negative in to from my LOC. Was going to tap it directly in to the rear speaker wires in the trunk but read that a lot of people prefer to tap in the wires going directly in to the OEM amp. Thanks!

Here is what I have gathered so far:
right plus- blue/black on grey connector-pin 8
right minus- brown/orange on grey connector- pin16
left minus - brown/orange on black connector wire pin 29
left positive yellow/black on black connector - pin 37
white on grey connector- control
