bad wiring harness

I just picked up a 96 f350, after a great deal of reading and scratchin my head I've come to find out my wiring harness on the driver's side valve cover is shot, can anyone give me a heads up on what parts I need to fix this issue? Thanks

Valve cover gasket and Under valve cover harness is what you'll need. How did you determine it was bad? What symptoms were you having?

Ok, I replaced valve cover gaskets ,internal and external wiring harness's, glow plugs, cleaned fpr screen. Now truck runs way better at idle, however it is still running flat at over 2000 rpms ...anyone have an idea?

What's your fuel pressure? That RPM is when turbo starts working it's magic. I'd make sure the turbo isn't shot. Could also be a fuel issue.

I'll check fuel pressure on Friday , also,I disconnected the EBPV and wired it open, I assume the EBPV is "open" when the rod on the valve is retracted towards the drivers side? I hope

ok, fuel pressure is 50 psi after IPR shim, was still running flat above 2000 rpms... until i unpluged MAP sensor, now it runs great above 2000 rpm and better out of the hole, idle is wacky tho... replaced MAP with new sensor and now I am back to where I started with it running bad??????
