I've been running a p28 on my h22, and recently switched to a p13. I threw code 23 (knock), and found out it wasn't even hooked up. I modified my sohc harness for the engine, so I found the H22 harness, and was looking for the knock sensor plug. I was under the impression that it was a one wire self grounded plug (goes to D3), but the only one I can find is 2 wire. Do I need to ground it to the chassis? Does it ground to the ecu? Does it hook up to anything?

 

It uses a 1-wire plug. Keep lookin' for it.

 

was your SOHC harness off a DX, because if it was I had to get knock wired in.. im assuming your p28 disengaged knock, and you had your v-tec wired up , if you need a plug I have a extra I would sell , its a rounded two wire plug .

 

harness is from a del sol s with a d15, no knock. The plug is not on the harness, so I'm running a new wire directly to the ecu. I guess I'm just going to try the 2 wire plug and see if one of them works.
