I have a 72 pre L thats had issues with the turn signals ever since i bought the car several months back. After looking at diagrams and being double jointed i have found that the car has very early flasher module with a late model hazard switch. I wired in a 3 pin flasher like shown on the diagrams and tried to put the ISO relay to get the light in the tach to work. The problem is when the keys is turned on the flashers start with out turning on the flashers with the lever. Am i missing something??? Stumped and going bald.
