Hey yall
So I just installed a new stand-alone harness from eBay because my old one was giving me issues and it’s had its time. So I installed the new and car fired up but has a super loud knocking sound. I know it’s nothing internal because the car ran fine on the old harness. I’m assuming it spark/timing related.

Getting a p0343 code which is for the camshaft sensor. And sometimes a p0355 and a p0357 for ignition coil.

Engine-5.3 Lm7 2001
Trans-Turbo 400
Harness-

Any help is greatly appreciated! God Bless!

Throw the ebay harness away and buy a good harness unless you have a lot of free time and are good with a digital meter.
