rb20 code 12

Got a code 12 on my ecu. Looked at the wiring and it has been lengthened but was done good. Cleaned the maf and the filter for it. Now car will idle then die randomly. Only part that looks to be bad is this
that bare wire runs all the way to the stock part of the harness bare. What is that and anyone have any suggestions
