Default 65 GTO dash wiring
Here is a drawing I made years ago, it could be of some help.

The adapter harness is a actually a copy of a 1965 Lemans-GTO part only. They do sell it new and I guess they say it can work for other years.

For true rally gauges in a GTO for years: 1966 and 1967 (GTO) the entire dash harness including the fuse block was unique to either with or w/o gauges.
