im going to attempt an LED swap in my car. i feel there are enough tutorials on here that i can manage it.

i have one question though for doing an 2 tone blue / white combo for the gauges, which LEDs on the diagrams that garage1217 posted are for the numbers and which are for the markers?

im going for a look like example #13 on here

any info on which ones light the different areas would be greatly appreciated

will post pics after successful install..... hopefully

im pretty sure you put all white and then put a vinyl on the back side for whatever color you want.

dont quote me on that though.

well.. i'm gonna quote ya... :P

yea... all the leds lighting up the gauges are all for the needles, and the entire gaugeface... nothing is really separated.

to get the two-tone look, it's all white leds.. and then colored vinyl applied to the back of the gaugeface.

lemme know if you run into any problems and need help.

Here are some more guide..
