Yeah buddy, your layout, works like a charm using my resistor/LED configuration As for the color code, not sure off the top of my head but I'll have a look tomorrow as I have some left over.
As for the painting, it was fairly easy...
First I got contact and placed it over all of the letters, next I got a stanley knife and cut around the letters, removing any of the excess contact so that only the letters themselves were covered. After all was prepared I coated the garnish with two coats of black enamel paint and allowed it to dry. To test if two coats was enough to stop the light I placed one of the LEDs behind it and sure enough, it did the trick! Then I got the white enamel, sprayed on two coats of that, allowed time to dry and peeled off the contact being careful not to damage any other areas.
Worked a treat as you will see tomorrow when I post pics! As I said, I'll probably get it color matched by a pro when I get my car done but for now, this is more than adequate!
