Didn't pay much attention to holes on the dash but was puzzled on this one as it's not shown on dash layout. I found out it is for a governor control if so equipped

I had a high beam (tell tale) light as part of my wiring harness but didn't have the cover for the bulb so I got a snap in bezel from Ace and an L bracket and hose clamp. Just drilled a hole where the bulb would be centered in the bezel and put a nut and bolt through dash and hose clamp for the ground connection hooked it up to foot switch and good to go.
