Cool. My ECU diagram lists CAN L and CAN H. Would a voltage test during cruise "set" indicate which CAN could be tapped for the hot side of the LED? Opposite side of LED to ground?

The CAN bus is a high speed computer network. You would need an intelligent device to decode the messages and light the LED when the appropriate message comes across.

What year is your TC?
