i am redoing the dash in my 81 Jeep, to include rewire some things. I went from the traditional big speedo with fuel and water temp built in to electronic gauges. If you are doing the same, you may need to wire up a ground and a lead 12V to the back of these gauges. I used the leads 12V from the other gauges so they would all be ACC. I am going to use where the radio cutout is to mount two of the 4 gauges I am putting in. I will cover the hole, then cut out the 2in holes. Pics to follow....
