I finally got around to installing the spark plug wires in the metal conduit tubes on the 1947 Lincoln Continental V 12 cylinder. I placed very small metal wires in the conduit tubes, taped the small metal wires to the spark plug wires and tried pulling the spark plug wires through. I started with the longest spark plug wires first. I used knocker loose penetrating lubricant on the spark plug wires. Some of the last few spark plug wires do not want to go through one of the tubes.
There is a wiring harness in side this tube and goes to the generator and the distributor coil resistors. I am wondering when the spark plug wires were installed in this conduit tube at the factory, was this wiring harness installed afterwards or before the spark plug wires were installed?
