This knock sensor sub harness is a must if you are getting a low knock sensor input signal code. Install is tedious and takes about 2 hours. If you have a loss of engine power and have the previous mentioned cel code, this is your fix. Thanks Z1!

The connector had one tab that didn't match. So I took a sharp knife and shaved off the offending tab. It was an easy fix. Then I assembled the cables and etc. My 2003 G35 has been running great since. No more error code. Thought someone might find this useful.

This fixed my P0327 fault code. The factory sub harness in these cars is very poor quality. Every time it was humid or raining I would get P0327 fault, and the car ran poorly.

Have not installed the sub harness yet but am very impressed by Z1's speed of service/shipping. I live in Canada and ordered the item at 5pm on Wednesday, I expected it to show up the next week but to my surprise it arrived at 11AM the next day. You guys rock!

Worked on my 2004 G35. Ordered Monday night in Texas and received on Tues. Shipping was unbelievably fast. A pain to get to to install. Will definitely use Z1 Motorsports again and highly recommend them.
