Classic Auto Air Installation 74 Dart Sport
I inserted the switch as far as it would go then drilled two holes in the plastic assy to secure it. I also had to shave a little off the plastic assy where the plug connects to the switch just so I wouldn't have to bend the switch connections. Worked out pretty well.
I also used the original control cable clamps when I installed the cables. I installed them as the instructions suggest as to how far to set the cable sheath in the clamp. We'll see how that works out.
Edit, update, You have to flip the switch around from the way I have it in the pictures, otherwise the fan will be on high and the lever will be next to the OFF position.
