1966 brake light question
So I've wondered about this since I got my car, and now I need to figure it out.
On the driver's side, the middle socket only has one wire going to it. I cannot find any trace of a second wire in the harness or in the socket. It looks like it never had a second wire, all the other bulbs on that side have multiple wires.
It is the same on the passenger side, one wire only in the midddle. The socket is missing, but there is no trace of a second wire in the harness on that side.
The bulbs do not currently burn on either side in any socket in any position on any function (signal, running light, brake).
Before I try and trace this down, is that middle socket supposed to only have one wire? It seems odd, but it is gone on both side, /shrug.
