| DIY-Cathodes in Doors, LED in Doorhandle
To get started with this write up. I'm assuming you already have some sort of interior lighting in your car, such as cathodes in footwells, or LEDs in cupholders. Either way, you'll need to run a wire from your existing switch to the door before you start following my directions @ feeding wires through the door bundle.
This is what we're working for 
Cathode light in the bottom of the front two doors.
----------
Run a power wire from your existing lighting's switch, under the front dash, to where all the wires from your right door bundle come into the car. If you can't decide where all the wires from the right door come into the car. Open the door, 8"up from the bottom, in the door crack where the hinges are, there is a black rubber boot. The wires run from the door, through this boot, into the car. Now under the dash, find where these wire's come into the car. It's pretty easy.
Remove front right door. Pretty easy- remove screw in door handle, remove screw in door grip. Pull.., disconnect two electrical quick-disconnects..lift door off
You are going to have to use a coat hanger to feed a piece of string, or wire through this bundle. This is the HARDEST part of the job, it's all downhill after you get this done. The boot can be pulled out of the door/car side, so it slides left or right along the wires inside of it. This will help. Take your time, and eventually you will have the wire fed through the bundle.
Once the power and ground wire are into the door, with the plastic on the door pulled back it should look like this 
Once into the door, you want to keep in mind where the window will go when it is rolled down, when routing your wiring. See the channel the window slides down in? It's in the bottom right corner of the above picture.
So, for the two lights in the door. Here's how i routed the wiring. 
The pwr/ground wire comes into the door, under where the window 'could' roll down to, up the inside of the door, and out above the speaker area. By 'out', I now run the wire between the cheap plastic, and the metal inside of the door, so it doesn't get in the way of the window. Once into the door both the pwr and grnd wire are spliced and split into two pairs of wire. One pair goes on to the door handle. One pair goes to the cathode in the door.
Lets first talk about the door handle.
The wires for the door handle LED run between the plastic, and the metal inside of the door as seen. Once we get to the top right of the inside of the door, we must feed the wires back trough the door (minding to go AROUND where the window will roll down into the door) and to the outside of the door where the door handle is. 
This picture shows how I fed the wire behind the plastic and around the window channel. You see the wire going into a hole in the door. Let me explain.
There are two rubber 'bump-stops' on the back side of the outside door handle. If you pull the handle up, you will see them. I simply removed the front one, and fed the wires through it's hole.
Find drill. Drill hole in INSIDE of handle, in same spot hole from removed bump-stop is. Just take your time, it's fairly simple. 
In the above pic you can see the wire running from the led (oznium.com), through the hole I drilled on the inside of the door handle, then through the hole from the removed bumpstop, and into the car.
The LED is mounted with double sided sticky foam. No issues in over a year.
---------------------------
Back to the cathode in the door.
First to prepare the door.
Take the removed door and set it down on a workbench.
I traced out where I wanted the cathode to sit, and then cut it with an exacto knife. If you do several passes over the same traced shape, it will slowly cut through the plastic with precision. 
Above is an example of how the cathode is mounted. I used two pieces of double sided sticky tape, and two zipties to secure the cathode.
The zipties utilize two holes each, that I drilled down in order to feed the zip tie down, then back up, and around each cathode.
In the above picture, the cathode power transformer is not yet mounted. 
View of the hole with the cathode mounted. 
You can just barely see the zipties coming down and then going back up. I ended up using black on the other side. No worries, you can't see the zipties once the door panel is remounted.
Finally one more look at how all the wiring is routed. 
The red lines show the wire once through the door bundle. The wire comes up and out above the speaker, splits into two pairs of wires. One pair goes to the LED in the door handle, and the other pair comes to the power transformer for the cathode. You can see here where I ended up putting the power supply, ziptied to the soundproof material in the door.

Questions?
***** Put three pictures in there in HTML instead of IMG format... anyone fix? The links @ photobucket are correct, just wrong format.

| Re: DIY-Cathodes in Doors, LED in Doorhandle I like the cathode placed inside even though it requires cutting an opening in the door panel. Thanks for the write-up! |

| Re: DIY-Cathodes in Doors, LED in Doorhandle Any night pics of the handles? Very interested in just splicing wires from my led door locks to go to the handles |
