I had a 70 Mach 1 parts car way back in the day and put the tach dash in my 69 sportsroof. I did more than just throw the tach dash in it, I pulled the wiring harness out also. I took harness up to my room in the barracks and modified so that the tach and idiot lights would work. I was dangerous back then, an avionics technician with a wiring diagram. It not only worked, I did the same thing to my 67 coupe, that is modified my main harness for the tach dash. Oh those were the days.
