70 something Ford van has a small dash panel on the right that has the right pull type light switch with built in dimmer the panel also has an ignition switch. I used both. the junk yard van still had the key in the ignition. 15.00 dollars for the whole panel.
To remove the panel in the van you need a philips screw driver for the four screws and then a pair of sheet metal sheers to cut the wiring as deep in to the dash as you can reach. Most of the wires will match the colors of the mustang harness.
the Knob of the light switch will pull out of the switch when a pin is pushed down. the knob and shaft will be about 5" long. don't force it!
