Haven't seen anyone do this yet, so i figured i give this a shot.TOOLS NEEDED:
Soldering iron
Rosen core
6 White 3mm LEDS (preferred) or 5mm LEDS
6 470 Ohms resistors
Breadboard
Dremel
sand paper
Flat head screwdriver
Hot glue gun
Heat shrink
Snap or slide connectors
First, remove the gear selector trim from the car. Remove the shifter trim, then remove the 4 screws holding the gear selector trim. Then remove the bulb socket. the gear trim is held by 4 plastic tabs, just lightly pry each one around. Disassemble like shown:

second, cut out a piece of the breadboard to fit it in the gear selector like so.
Goal is to try to get it sitting as low as possible so more light output can dissipate to reduce hotspots.

Third, Wire your LEDs:
Add a dot of hot glue on close connections from shorting out.

solder on + and - connections, wrap w/ elect tape, then heat shrink. afterwards, lightly sand off the tip of the LEDs to reduce hot spots if you want.

fourth, refer back to second step. place board as low as possible, then hot glue both ends.
Results:
it appears a rather bluish b/c of the blue overlay underneath the display. theres nothing you can do about that.


now go cut off the stock bulb harnesh off and then connect it to your LED wires:

reassemble and your done

one other side note. for the last 2 LEDS displaying gear 2 and gear 1, you will be able to see some of the white and the led itself off to the side in the passenger seat, as you can sorda see in the above pic already. Not necessary but i went ahead and took care of it. just get like 1/2 inch high, 1.25 inch long piece of plastic and just stick it beside it. you can use black electrical tape as well.
