I don't have a 68, so just a guess. The right override switch is closest to the wiper switch and controls the wiper door. The left override switch is closest to the headlight switch and controls the head lights. That's at least how it works on the other cars.
Hi R,
The info I have to refer to indicates this was the placement of the vacuum overrides and wiper 'stop' **** on early 68 NON a/c cars to at least serial number 9774.
On all a/c cars, and others after that serial #, the **** moved between the vacuum overrides and the trio moved directly under the steering column.

Later placement.
This is placement I have always seen. But, I can't see that block as an aftermarket item, I don't have a/c

When 68 production first started, that was the placement of the switches, with the wiper motor **** to the left of the pull downs, and the whole assembly mounted under the tach.
Later the bracket was moved under the column, and the wiper motor switch was centered between the 2 vacuum switches. As far as the VIN when the change took place, I'll take Alan's word on that.
The bracket and connector are pretty rare, especially that connector. I've only ever seen one other one, in 40 years of playing with Corvettes.

So it is original. I don't think I'll find a replacement for that connecting block
