1983 300D lights on dash, where do they feed from?? Some time they all light up and some time only glow plug light up and some time none light up.
Have unplug all connectors clean, lub and replug. Act like a bad connection, so would like to know which is the right plug in, so can super clean it and solve problem.

Thanks for any help you may have for me.

Thanks,
Dewey Faircloth
