P0328 engine problems

[Blanco_SB]

Hello, I have a 2004 G35 coupe and it was throwing a ghost code(No Engine Light)for P0327 which I found to be a burnt knock sensor harness so I replaced with a steel braided one from Amazon and also replaced the sensor as well with NTK 72906 kne20. So I put everything back together and now I have a ghost code for p0328, the exact opposite now of the low circuit p0327. It is now reading a high circuit. I don’t know if the non oem braided harness is the problem or if the connector from the body harness that connects to the knock sensor harness is bad. The body harness connector didn’t get burnt, but I did have trouble disconnecting it and maybe the wires got loose from the connector. Any advice would be appreciated, I’m tired of the loss of power and bad mpg.
