Default knock indicator and shift light.
I made a simple test.
A 1k resistor in series with a large high intensity LED.
I connected one side to the 12V feed to the ESC module and the other to the output wire.

( click the pictures to enlarge )





And a short video of me tapping at the exhaust. You can see the LED flashing when a knock is detected.

I made two LED's with resistors and cable. I installed them in the dual pillar pod. I am going to use one as knock indicator and the other as shift light.

Cool idea...

You mentioned shift light--what are you using for the trigger?

Since the ESC stuff is on the memcal for the 730, you might have to do something like this... http://www.chitownsyty.com/html/tech/led.htm
