Is this knock sensor bad? Also where is the knock sensor wiring on the harness?

HI guys,

After getting my 97 Ka into my 93 s13 I started it and it had a rough idle and now is not starting at all. The codes I am throwing are 12,13 and 34. I cleaned the MAF and got the old knock sensor off. It has a crack down the hard rubber on the outside of it - and the wires were pulled out of the harness plug? Luckily I used my engine harness when putting this engine in. But I cant find the plug on my harness. Is this a 2 part harness (Knock sensor plugs into a harness on the block which then plugs onto the engine to ecu harness?)?

So it this knock sensor still good? And where on the harness is the wire for the Knock Sensor?

If it's cracked I don't know if I would trust it. Wouldn't hurt to get a new one, that's for sure. The knock sensor is plugged in where it meets the block and the harness runs up front to the motor, you can see it in the pictures.


This is where your knock sensor connects up front.

This is what the knock sensor plug looks like.

Blurry, but these are the two wires in the knock sensor.

I wouldn't trust it, but the only way to truely tell is by getting a volt meter on it.
