    Insturment cluster help!

    So I took out my insturment cluster to paint the needles. When I put it back in, I plugged everything in right. Now the speedo, tach, backlights and obc do not work. I checked the fuses and they are all good. I did use a drill to screw the screws back in, and it did cause a lot of vibrations and the needles were jumping. Could that of somehow messed the cluster up and caused these other things not to work?

    Edit: just want to make sure I have everything wire correctly. I have the blue, yellow and white plugs in their corresponding spots. I have two bulbs plugged into the only spots they can go. What about the plug that connects to the green peice under the speedo. Which spot should I plug it into. Am I missing any other wiring? Yeah, next time I'll take not of what goes where...

    If anyone cares, I pulled it again, and somehow burned the shit out of some of the board. So, anyone got a full cluster for sale?

      you probably caused some breaks in the wire traces on the board itself. i have a post on here somewhere describing what i did to fix the back lighting on mine

      in summary i used a DMM to find the breaks in continuity and repaired them. it wasn't hard but took time and some electrical know how.

          Yeah, I read your thread. I don't think this would be too easy to fix.

            hell, you could probably fix it. or at least give it shot. it's not like you have much to lose except time.
