Ok i did a search and read that the blue wire goes to the knock sensor pin on the ecu. but my question is, does the black wire go to the ecu also or is it a ground wire. and if it is a ground wire, where do you guys typically ground it?

btw this is for a y7/y8 mini me

On my mini me, my knock sensor only had one connector..

I dont think you have the right sensor.

The knock sensor is a 1P sensor. And that plugs into the ecu. Take a pic of what your looking at. The Knock is under the manifold between cylinder 2 and 3

i already put in on. there was one connector but it had two wires coming out of it

The knock sensor is 1 wire. In your case (obd2b) it goes to the c3 pin location. You may have it mixed up w/ an IAT plug somehow.

if that is the case, then can i still use that plug? and just not use one of the wires?

Luserkid

you need to use a 1P plug.

what if i dont? i just bought this from hatchi on HT and he said it was a knock sensor plug. That took like 10 days to get to my house. Am i just going to have to find out if it works by doing it myself?

You can use the plug you have but, make sure the wire that will come in contact w/ the pin(in the KS) is the wire you are running to the ECU. Alot of the plugs (i.e. IAT,KS,CTS, IACV etc.) have the same design.

does anyone know which wire would come in contact with the pin?

Look at the KS. It will look like an IAT plug but, it will only have one metal prong sticking out of it. Whichever side of the plug comes into contact w/ the pin is the wire that should be ran to the ECU. It's very simple.

yea but that means putting the car back up on jacks and pullin off the oil filter and yada yada yada. there are two colors on the plug. black and blue/black, any idea which would have the prong?

Try them both, The one that doesn't throw a CEL is the right one. You need Trouble shooting 101

tap both wires to one and run it to the ecu if you don't want to figure out which one goes to the pin on the ksensor
