So this was going to be a temporary solution for my iPhone then I really liked the idea of having my unused switch turn into a plug for my iPhone. While I was at it I had a spare blue LED from my door handle project, and decided to change the green light to a blue one.
First things first:
I have a an 11/2003 R53, so my tools maybe different then the ones you need.
I used a T15 to remove my down tubes and the center part of my dash.
Then using the same T15 I removed my switch panel and radio.
Once the switch panel is out there are two (2) clips on the bottom to remove the front half from the rear half.
Then there are three (3) clips separating the two sections of the rear portion. Be careful not to loose the white spacers inside. They have the potential of flying every-which-way.
Now the next few steps are if you want to change the LED color:
Grab the silicone board and twist and remove the green light.
I used 5mm LEDs so the hole needed a little grinding before the LED would fit. Once done it should look like this:
For me, the side with the pink dot was positive. In LEDs THIS DOES MATTER. The short lead side is positive, the side with the flat spot is negative.
I used a 5V LED so the resistor I needed was 270ohm, if you're not sure
HERE is a calculator.
Soldered in:
The leads must be cut to fit in the plastic housing. Everything must be as small and compact as possible without short circuiting.
DONE! With that part. If thats where you're stopping then just make sure everything fits back together and use the steps in reverse to finish up.
Now if you're moving on, hopefully you have the OEM Auxiliary jack.
The heat-shrink tubing needs to be cut off the end so that the wires can make the bend in the housing.
Then the hole needs to be drilled in the front of the switch plate. I would do this slowly and accurately, as this is what you will be seeing everyday. I started from the inside on the first pass to get centered, and then switched sides to make sure the hole was clean.
And this is what it looks like screwed in, but don't waste your time screwing it in yet, you'll just have to remove it later.
Now you need to drill the hole through the rear outer casing, circuit board, and the white rubber.
I used a spot near the passenger window switch because there aren't many contacts there. You can see in the picture where:
ALMOST THERE!
the wire needs a place to go, that's out of the way. So the little plastic walls need to be cut.
A better idea of what your looking at with the routing:
Now Clip everything back together!!!! Make sure you put the white spacers back in if you took them out.
I took it one step further...
And final assembly:
