Quoted from Chosen_S:
Curious on the LE... is there a hook for the colors of the ramps... what I mean is, can I connect somewhere to have a set of rgb leds? I’d like to have something outside of the game be controlled by the ramp lighting system.
There's no easy plug to go to, but conceptually it's not difficult. It might be fiddly, and there are varying degrees of quality job you can do.
Easiest (but crappiest) way is to just hang off the individual colour connections on the actual LED. You would have to join wires up to the R, G and B pads/traces of the factory LEDs and power. This will light up your LED at the same time the factory one is lit. Lots of potential problems with this route though as you don't know the safe current draw and you will short something out probably (ask me how I know, ).
Next best is to use those same connections to drive a transistor gate and independently power your LEDs. I would favour this and can help you find the best place to tap in if you want (with the aid of pics..I sold my LE).
Best way is to intercept the data line, decode it and use the signal to drive your LEDs as in the second approach.
