remove dome light fuse. its located in the fuse box under the hood. i believe it was the 20 amp fuse. remove the steering column covers-- there are two, both are sandwiched around the column. lots of screws. get on ur back, look up, remove screws. (i removed the under steering wheel panel to help get access to some of the screws and wiring plug.)
Once thats removed, you should see the ignition ring clearly. it's held in place with one set screw, phillips head. I chose to remove the entire wire. to do this, simply twist and pull the light bulb unit from the ring collar. follow the wire back under the dash and unplug so now you have the entire wire. this was easier for me because i had to cut, strip and solder in the LED for the ring side of the wiring. (instead of trying all that under the dash while it was still plugged in) I got a "typical" white LED from radio shack and a 470 ohm resistor from radio shack. cut the wire end where the bulb is, strip the wiring, solder the resistor to one of the legs of the wire, positive or negative, doesnt matter. What does matter is how you solder the LED onto that. positive to positive & negative to negative. I used the original bulb housing to hold the LED, with a little bit od hot glue, install everything. put the fuse back in and open your door, it shoudl come on. doesnt get hot either. it was little more directed light than i wouldve have liked, but it works very well. you could sand the tip of the LED slightly to diffuse the light if u wish.
Also, you could use shrinkwrap to seal everything, but i just used electrical tape. Mainly, you just want to make sure the wiring doesnt touch anything, but thats kinda obvious.
This is how I did it. There may be other methods. It's really not hard, took me an hour because i was being careful. good luck.
