I installed a new headlight switch, I have removed the dash and continuity tested each bulb, socket, and ribbon. All the bulbs are new, so I'm confident its not the dash components.... Why is the dashboard not lighting up?? I cannot seem to find a wiring diagram for the dashboard harness, so I have little to go on as it related to what wire is power, ground, each component...anyone have any insight. any assistance is appreciated.


Yes, its been some time, the car is coming along nicely....once the electrical demons are out, seat brackets and interior!

Check the instrument lamp fuse first. If it is good, remove the fuse and check for power on each of the fuse clips with the headlight switch turned on and the dash dimmer turned to full brightness. You want to see power on one of the clips. If power on one clip, everything upstream of the fuse is good and you have a break between the fuse block and the cluster. If no power, you have a break between the headlight switch and the fuse block.
