I was wonder what the 2 wire numbers are? They are missing the tags. Any help would be great.

The two together are 27 (Instrument power) & 85 (Accessory).

The other 2 are 12 (Ignition) and 11 (+24V). You'll have to ohm the switch out to figure which is which.

Wes,
If the pinouot is the same on all of these switches I think I can help.

I see the ridge for orienting the switch in the dash. There is a small pin on the front of the switch that corresponds to that ridge.

On mine, facing the same direction:
27 and 85 together are at far right.
11 is in the middle at the bottom,
and 12 is at the far left.

Hope this helps.
Brian

BTW,
the one labeled 25 in his photo is supposed to be 85, as you noted.

I suspect the original wire tag was damaged where the 8 looked like a 2.
