Cluster lights/Head Lights not working - Help Please

[jobsforu]

I have a 71 c10. Have new headlight switch and just installed the new Heavy Duty Headlight Harness from LMC. Also replaced all cluster bulbs with new green high light bulbs; aal from LMC. Here are my problems. Any help will be very appreciated:
1. Upon completion of new HD Headlight Harness, headlights worked great. Then I started working on Cluster lights to determine why they would not work; they were before with the old type bulbs. Somewhere along the way, using the headlight switch - I drained the battery and had to re-charge it. But, after the re-charge - the headlights did not work. I have cleaned all of the ground connections and reattached; still do not work.

2. Is there supposed to be a ground wire coming from the gauge panel/circuit board to metal under the dash? If so, I do not have one. Anyone know exactly where I hook it to the back of the gauge panel and where to run it?

3. Also, is there a ground wire from the new headlight switch that I need to connect somewhere? Anyone know what color it is and where it should go?

I have also cleaned all of the battery grounds and replaced. Also cleaned the plugs and connections for the dimmer switch and re-connected. Fuses are good. Yesterday installed new headlights just in case that was the problem. And, I have one wire with a bulb coming from the steering column that appears it should be on the gauge panel somewhere - but have no idea where it goes. And, when I rotate the headlight switch it dims the heater control light so I know that's working. As I said - any help will definitly be appreciated. Thanks, Doug
