i bought my 92 rs with gauge overlays installed and then found out there was no light coming through it. after going to replace bulbs i found a mess of wiring and im not sure how to get these to work. i am thinking they are reverse glow gauges but im not sure where to wire it to or if they still work. i had checked them with the red and black wires coming out of the dimmer but they wont come on.
