Are you trying to relocate the factory radio down to the lower console? Don't!! I did that I can tell you it's a waste of time. The reason is the default Becker radio has a horrible viewing angle. You cannot see the display unless it's on the top console. It doesn't matter if it's day or night. You will have to move your head to the correct angle to view it.
My year has the HVAC control on the bottom and the CD storage on top of my lower console so I can only advise you for one part but it should work the same. What I did was use a wire hanger and a zip tie to route the radio cable and antenna to the lower console right down the middle pass the "triangle of death". Run the metal wire hanger up rather down creating a end from the top and the other end at the bottom.
