Thanks to William and Seth!!

I just wanted to say thanks to the original author, William Quiles, and to Seth for posting this flawless DIY. I've made use of the wiring diagram and front door mounting ideas to upgrade my 2005 330ci with similar a/d/s/ equipment. I'll post a new thread with pictures of my equipment board and additional information.

For now, I wanted to add my contribution to the wiring portion by posting a diagram I made that maps the pins from the connectors on the harness to the internal connections of the amp. I purchased a used non-HK amp from a 1999 E46 sedan and removed the guts except for the small PC board the connector is attached to. The board has six mini connectors on it that are straight-thru signals.

I used 24ga phone wire, solid core, as "pins" to insert into these connectors and mapped the appropriate pins to terminal strips like the ones William used in his original DIY. Viola! A connector for the harness without cutting the harness!

Attached are two pics of how my "connector" turned out, and the pin mapping diagram.

BTW, I made one mistake when I created this. I ran the +12v remote-on wire along with the pre-amp connections. This has resulted in a low level buzzing noise since this wire has power while the stereo is on. So, I've re-routed the wire to alleviate the problem.
