The plug on the harness doesn’t fit the engine harness. Made in China, sometimes you get lucky with Beck Arnley and it’s made in Japan. I had read other complaints about the harness not fitting on cheap Chinese knock sensor kits, so I just ordered a new harness ($60), and two new knock sensors ($165 each) from Toyota. The sensors are under the intake manifold, so I don’t want to do this job again.2004 Camry, 3.0 V6.

Reason for the one star is when I recieved this, the box said 185-1794, my part number was 158-1794. Amazon sent another one out with same wrong part number. I placed call into part company beck/arnley, wondering if label was wrong. After a few days I recieved a call back stating that the part was correct but someone labeled boxes incorrectly. Obviously not Amazon's fault but because of the incorrect labeling by beck/arnley there was a huge delay in fixing my car. Since harness/knock sensors are located under intake manifold, having the correct part was imperative because this is a 4+ hour job.
