i did mine with my single cam over 2 years ago.
The light still works too.
It's not hard, if you're set on doing it you need:
Wire
Lightbulb
Transparent folders 5 pack (diff colors)
Computer
Printer
basic wiring knowledge
screwdriver
time
I wouldn't do it again, but it did help me troubleshoot when my VTEC was cutting in and out due to a wire tapping ground.
