Flatblu4748, thank you for the diagram. More elaboate than I was thinking with the key warning buzzer but I bellieve I understand the basics for the interior light. I still need to detemien what would be invovled in isolating the dome light mounting bracket from the bulb base.
MNSmith, those footwell lights seem like a nice option to consider and could easily be wired in using my harness connections for the dome light using the same power source and door switches/headlight switch to turn them on.
For the moment I have about 100 other wiring related tasks so this one is pretty far down the list.
