hi, i just got an alpine s-630 changer w/ a blitzsafe adaptor for a '99 328i. My first problem is locating the connecting pins. I removed the carpeting on the left side and found some unconnected wires, but the only connectors I found were a 3 pin and a 26 pin one (the adaptor needs a 3 pin and 6 pin). I'm thinking this isn't the wire I need so where do I find the correct one? Is it under the plastic tray (if it is any tips on removing that tray would be appreciated)? Finally, where do you think the best place to mount the changer would be if I'm not concerned w/ trunk space...the rear shelf or on that plastic tray? Sorry for the long post, I just wanted to be as clear as possible. Thanks.
