Default Codes and electricity

I´m setting a few codes and beleve it´s because the wire loom is getting ground somewhere in the negine bay and messing with the sensors

Where is a typical place for the loom and computer to get ground?

It would be better to say what codes i don´t have

I have codes 12-16,21-28,32-32,36,41-46,51-53,55,61-69 and 71

I have removed the AC,Smog system

Err12: No DRP Pulses
Err16: Lo-Res Fail
Err26: QDM3 CCP Electrical Fault
Err27: QDM3 EGR Electrical Fault
Err28: QDM3
Err36: Hi-Res Fail
Err41: EST Open
Err42: EST Grounded
Err43: ESC Fail
Err53: System Voltage Problem

These are the codes i´m linkning to my fault

Ignition system is compleatly new,from ignition to plugs,Fuel pump and injectors,Fuel filter new ect...

i know about the checksum error but that is my fault and i have fixed that,but still the same
