1969 Barracuda Dome Light Question

By the way if your car has the A01 option then there is a very short jumper harness that goes between the connector you originally showed and the passenger side harness. The jumper feeds power to the trunk lamp! As I show my car regularly I have a plastic blocker for the trunk light switch as the trunk is usually open at the shows. No need to drain the battery!
My car does not have the light package. What bulb are you using and where did you get it from? The ones I ordered from year one in the interior bulb kit they gave me are standard bulbs and don't fit.
