I checked and there is not a brand/ model number on the switch. I purchased it from Classic Parts and the wiring harness for a one wire alternator. It attaches to the steering column and the 4-way flasher has a red knob that pulls out. It has 7 wires. The wires from the parking lamps: 1 goes to the terminal board on the fender well, and the other goes to the switch. It follows the old post by KCMONGO that has a colored and numbered wiring diagram for 47-53
