Hey everybody; The marker lights are there. All of the wires connect to the original harness with stock plugins in the front and are included in the taillight harness plugs. There are no added splices or connections. The lights appear to be as old as everything else on the car. Dick B. is the most knowledgeable person I have ever met when it comes to Imperials in particular and cars in general. I thought these looked to be factory installed, and he verified that opinion. Incidentally, he decoded the fender tag to reveal a build date of January of 1967 for this car. Larry
