Help! grounds location on a 1964 corvette

[wayneb661]

having a bit of a time with a 1964 coupe and some grounding problems, and with all my factory shop manuals they show splice connection but not locations and would like to clean up connection other than adding more ground paths to neg battery. this is a factory 34,000 mile car with no added extras.blast to work on. hope everyone had a great thanksgiving day and god bless our troops. thanks Wayne

Let me see if I understand

You want to open the factory harness... and ( i assume ) solder & crimp the grounds... in the harness ?
