finally figured it out?

[280zgod]

hey everyone its been awhile. alright some time ago i mentioned that my dash lights hadnt worked since i took out the stereo in my 75. well i think i finally figured it out, i hope. your opinions would be much appreciated before i proceed. alright in the schematic it shows a green wire with a white tracer connecting the ignition to the light switch in the combo and then also to all of the dashlights and headlights and such. the headlights have their own ground up front and are on a diferent ground from that of the dashlights. they have always worked. but the dashlights i believe have their ground through a red wire with a blue tracer as shown in the schematic. this went to the stock radio where the radio acts as its ground, if im reading the schematic correctly. if anyone knows the answer to this it would be nice cuz once its light im going to try this grounding theory of mine out. so i have no radio and if i ground this red wire with blue tracer im assuming my dashlights will once again work. if anyone could take a look at the schematic and give me their opinion it would be much appreciated or if anyone knows the danger of grounding that wire please let me know. once again its the red wire with a blue tracer that goes to every dashlight and then to the radio which ijm assuming grounded the circuit. thanks for your time and i hope that wasnt too confusing. ~Jerrod
