Default DIY Ambient Lighting install 2012 2.0i

So i worked on this most of last week, lots of research, lots of time testing different resistors, lots of time under the dash figuring the wire run as well as getting throught the stupid rubber elbows in the doors. here is the result, i didn't take as many pics as I would have liked, and I can take more in the future as I will be taking my door cards and radio out again soon.

What I ended up with was:
1. 1 LED in each Door card
2. 1 LED in each footwell
3. 1 LED in the cubby under the radio
4. 2 overhead LED's to light up the center cupholders similar to VW style.

all of these lights are very subtle and not distracting in anyway, I dim my lights as much as possible when I drive at night, so I really hate distracting light, but then everything is so dark I have to turn on the map lights to find anything. now I don't have too

Parts used:
2x 5mm through hole, 15* viewing angle, these are the overhead lights
5x 5mm through hole, 120* viewing angle, these are the footwells, etc lights
wire
resistors, all 1/4w:
2x 2.2kOhm for the overhead; yields a circuit with 2.3mA of current which is perfect IMHO to emulate the way VW does it.
1x 10kOhm for the drivers door, 1.2mA of current
1x 4.7kOhm for the footwells, cubby, passenger door (all same circuit), 1.2mA of current
bullet plugs if you want everything easily removable

tools/reference:
http://ledcalculator.net/ I used 14.4 supply voltage, 2.4v for the drop
https://www.youtube.com/watch?v=88hMp8IjBGE
http://www.jeepforum.com/forum/f67/h...mited-1320369/

once I finally figured out the resistors and where i wanted them the process was pretty simple.


Overhead:
these lights are on whenever the key is switched to ACC or ON, just like the mirror
power from mirror wire --- resistor --- (+) side -- LED -- (-) side -- LED -- ground

1. remove overhead lights
a: removed map light lense
b: there are 2 screws that need to be removed
c: unit will come down easy, just disconnect the plug up there.

2. for the power I tapped the mirror connector, as far as I can tell there is 1 key-switched power source on the connector, the other 2 appeared to be ground.
the wire you need to tap either with vampire clips or by cutting/soldering is the only wire with a white stripe on it. I cut the insulation and soldered to it.



3. LED placement
a: I drilled 2 holes, one on either side of the microphone
b: i added a few plastic spacers similar to what the post in the reference section shows on the jeep install. this helped to get the led recessed enough that it isn't distracting at all and just created the ambiance rather than always seeing the source.
c: soldered up my LED's and resistors and ran the wires.
d: i used plastic/vinyl adhesive for the LED's and epoxy for the spacers.



4. reinstall.




Footwells, cubby, door cards:
for these i made 2 circuits, 1 for the door side, and the 2nd is for the rest. this allowed me to simplify the wiring going through the door elbows as I didn't need to pass 2 wires through the drivers door. for the power I used an "add a circuit" and plugged into the illumination fuse that way the lights are on whenever the lights headlights are switched on (either setting).
The overall lights are so dim that you don't really notice them w/o something down there i.e. shoes, a water bottle, etc. I couldn't even take a pic because they are so dim, I even tried a 4-5 second exposure and all i got was a black picture. the lights are equal in brightness to the cubby under the radio.

Drivers side

circuit is like this:
power from fuse box --- (+) side of LED -- LED -- (-) side -- resistor --- ground
1. Fish wire through elbows, the video posted above is pretty close to in the process. it is a huge PITA if you haven't done it before, it took me a while to figure it out.

2. placement
a: I went at the back side of the door cubby shining forward, I think if i were to do it again, i would do the top shining down, and I just might try it.
b: drill the hole 3/16" is pretty close, otherwise it was a number 10 drill bit IIRC
c: glue in place



3. I used bullet connectors for everything in the event I need to remove things like the door cards to install MLV and RAAMat in the future



4. Ground the circuit to a bolt in the door. there is one pretty much in the bottom center that I used.

Footwells, Cubby, Passenger Door
circuit is like this:
power from fuse box --- (+) side -- LED -- (-) side -- LED -- LED --LED --resistor --- ground. 4 total LED's on this circuit)

1. I started in the door and worked back to the fuse box
a: it is an identical process to drivers side

2. passenger side footwell
a: there is a spot down there for i believe the factory footwell kit, so i used that hole for the led placement. i just zip tied the wire in position to hold the LED there as it is way to small for the hole.

3. snake wire into area under radio
a: remove radio bezel
b: there is a spot for a factory light, but we don't have one, i used that. I made my own mount and drilled a hole at around 30* so it would shine through the hole and forward. the LED itself is mounted about 1/2" above the factory hole




4. snake wire under steering wheel
a: due to airbag there is no mounting I could see for a light from the factory. I just zip tied it to a bundle of wires and worked out just about perfect



5. run wire to fuse box

here is a picture of the cubby and footwell. I had to put a piece of white paper down there to even get the light to show up. it isn't that bright. the brightness matches the cubby



and the door cubby, not really this bright, it is a bit overexposed to get the light to show up.

Nice job. Looks really subtle and clean.

Very nicely done. Thanks for the awesome write up. The overheads look great and useful.

very nice work. Even I am thinking of adding more led light to my car.

I wish I could post better pics of how it looks but it is so subtle that it isn't picked up by the camera

i wish i was good with electrical work, no clue on how to set it up unless its a splice and tap in. =(

This isn't any different.
The power comes from the add a circuit, run the wires, places the leds, and ground it at the end with a resistor

any one know where to tap into for footwells to come on with map light? i tried last weekend but, came up empty after splicing into a couple different wires.
