Headlight Switch: got it, but how to pull it?

[TomShilling]

I can reach the headlight switch in my 71, and I can feel the positioning of it, and I know the harness plugs into it from underneath...but how do I go about replacing it? Does the harness have a release button somewhere? Do I just pull on the harness to get it off the old switch? It seems as if the headlight switch is just attached to the pull knob on the dash and just hangs there... I know it has to be easy to replace, how 'bout some tech help here?

Thanks!
