Yes there are holes for gauge illumination on the left and right side of both the gauge and speedo clusters. I guess it's just a matter of finding the right wires to tap into as the connections are hard to get to and wires are bundled and wrapped. If I take out my gas gauge would I be able to tell if it was fried, like a broken connection i.e. a light bulb filament, and if so is it fixable (solder)?
