Where this harness ties into the main wiring harness, the plug is not correct. It is notched on the opposite side and can not connect. It should be shaped like the picture i am uploading, but if you look closely, it is incorrect.

ok

This was a perfect fit for the knock-sensor I purchased...although the wiring was a little different colors than expected. I came back to edit this review because I was looking at a few of the other comments which weren't exactly fair. The color scheme of the harness IS reversed, but the polarity is correct with respect to the shielded wire. Instead of a foil-type shield, there is a braided shield of high quality, which weaves into the stock wiring nicely. If you're doing a knock-sensor bypass, I recommend splicing the wires at their first junction, tracing back from the sensor...that way everything reaches nicely to any of about three potential knock-sensor relocations. Works great...thanx.

Looks well made, however even though listed for Nissans it will not work.

didnt fit the knock sensor as specified. Had to cut plastic tabs off the knock sensor connection in order to get this to work. Also, it appears that the ground wire in this isnt connected to the connection at the knock sensor? is that correct or ? once i modified it though, i got it to work for now, we will see if that continues.

Worked

This didn't fix the code being thrown, but apparently it's a very common code and won't actually turn your check-engine light on.I attached mine on the outside of the block as per the youtube videos, instead of disassembling the entire head.

So needed to get the knock sensor from under the dam manifold
