PART THREE: Installing the Guts
For ease of understanding this DIY I've taken the liberty of labeling the Harness Head Connectors as A, B and C.
This labeling is only specific to this DIY and not used by Parrot or Connects2.
The A Connector
is what you have in your car right now. It is what connects the car to the BMW Business CD53 Radio. With the exception of the possible Data Link mini connectors that attach to the bottom section brackets
(you may or may not have these Data Links in your car's A Connector depending on whether your car has prewiring for the CD Changer or AUX input/Sirius/Ipod Data Links)
these are all the same on all BMW E46 vehicles from 1998 to 2006.
The B Connector
. This is what will replace the function of your A Connector when you install the kit. Or a better way to say this is that it will take on the role of the A Connecter in connecting directly to the CD53 Radio and also carrying any Data Link connectors that you have going into the Radio.
The C Connector
forms a connection with the original A Connector in your car thus connecting the entire Bluetooth system AND CD53 Radio to the rest of the car (IE. for power, ground, speakers, etc...). This C/A Connection is the only thing that adds difficulty to the DIY as it is hard to tuck away behind the Radio when replacing the Radio unit. So we must set the C/A Connection above the radio space and to the side of the upper Center Vent space.
