I need the GM part # for the harness that is under the intake on an LS1. Goes from the knock sensors out from under the intake to a small connector. I've done several searches to no avail. A dealership gave me 10456603, that coincides w/ the knock sensors. I need the actual wiring that connects to them.

P/N I get is 12167120

I'd suggest calling SDPC to check that out. >>-->

Thank you! I am getting a PO327 code, I plan to replace this harness and both knock sensors. Hope this fixes it.
