Xoutpost.com - Aux install with Buisness CD

I recently purchased a Aux cable from ecs tunning (part #82 11 0 149 389) and iv read the how to post for installing but only found it for Navigation built in x5's. I was somewhat confused on where to put the wires in, either the head unit or the actual Business CD. So in case anyone is confused i am doing a small write up which hopfully some will find helpful.

First step was to remove the Head unit which can be found here

Than to move the Business CD out. Its held in place by two screws, Not sure what they are but i believe its a T10. They are pretty apparent but the attached picture will show you in greater detail.

The next step is to carefully pull out the Business CD and take a look at the back. You'll see that there are lots of wires in the back of the unit but the one we are interested is the plug that is BLACK, next to the white.

You need to remove the Black plug in order for you to insert the wires from the Aux cable. Brown plugs into slot 10(carefully read the left and right side inorder to know what number is what slot). Red is 3 and BLUE is 4

After this is done all you need to do is feed the wire to somewhere you would like and drill the holes necessary. Hope i helped by contributing a little:p:

***EDIT***

In the picture U see that there is two sets of wires on the same white slot, YOU SHOULD NOT HAVE THIS, instead there should only be one set of BROWN RED AND BLUE here already if you have a CD changer, The white cable slot should not be moved because that is not what you are after. the black plug is the goal.
