As far as the knock sensor's go, you'd have to check the outputs/inputs on the microtech to see if there's a channel that can read them. Most good ECU's have this feature, but I'm not sure on the microtech. However, what I do know of the microtech is that it has EXTREMELY limited inputs/outputs available, IIRC, the LTX12s only has 1 auxilary output to be used for a fan, fuel pump or whatever. So if I had to guess, I'd say you can't hook the knock sensor(s) up to the box.

But check in your manual.

You really can't hook up a light to the sensors themselves, they just create tiny amount of voltage based on the level of knock. And there will be a threashhold where you have "knock" but not enough to worry about and this level varies between engines and sensors.
