Wire diagram of knock sensor -> ecu

[alansupra94]

Does anyone have it or happen to know off hand what it looks like? I am very confused after looking at mine and seeing 2 wires + shielding. 1 white, 1 black and shielding.

I've been curious about this as well.
I've had the tail on the KS fall apart or get broken on a couple cars, but i've been able to repair it. I still am curious about how the wiring works though. It seems a bit strange... almost as though the actual sensor only has a single wire going into it.

Indeed only 1 signal wire is used on the knock sensor

There's two shielded wires under there. One if for the knock sensor, with 1 conductor. The other is a 2 conductor. I can't remember what it's for off the top of my head though.

mitsuturbo: The knock sensor is grounded through the shielding on the wire. The shielding is crimped to a short bit of wire that goes into the sensor, and to a chassis ground by the ECU.

I really wish I knew what the conductor is suppose to be hooked up too. I found it grounded but it was done by the previous owner so who really knows.

I almost want to say it is ground because it is all black...unless Mitsubishi is messing with me.
