Most gauges 47 and earlier do need a ground because they are the magnetic type with 2 wound electromagnet coils inside to move the needle. One of those coils needs the ground and the other coil gets the sender wire. 22nd and later series gauges are the heater operated bimetal type and do not need to be grounded because the heater is wired between the two terminals. Only the regulators on the years that had a regulator need a ground so that might help with your under dash mount
