Knock sensor pin location??

Ok me and my mechanic was wiring up my AFC controller and we could not find the pin location for the knock sensor!! Anyone happen to know which pin it is? Thanks

The knock sensor is in the back of the motor under the intake manifold "right next too the starter". You could tap the wire there if you need. If thats what your doing. What is it that your trying to do with the knock wire anyways?
I would find out what the knock is first just too be safe.

Ok thanks guys im looking for the pin on the ecu so that i can hook up my afc and be able to monitor my knock. Thanks for the info its greatly appreciated i was searching on magnusmotorsports.com and it did show it on the ecu pin location diagram so we was like uhmmm ..

You can't monitor knock with the SAFC. You'll get a reading, but it won't even be close to what the actual value should be. Don't waste your time hooking it up.

Even if i wire it right into the knock sensor itself?

It still won't work. The knock sensor on a DSM is basically a microphone. The ECU "learns" what is considered normal noise and then calculates a knock sum based on this learned behavior. So your SAFC might report 200 counts when the ECU sees this as normal and not actually knock.
