Don Scott sent me NAPA part number SL-169 for my CRII.
Below is a photo of mounted switch. Hard to see, but he switch has a metal flange that goes on the pin of the brake pedal BEFORE the spherical rod end (which screws on to the brake booster rod). I think the pivot bolt for the pedal has to go in last to permit assembly. Real fuzzy on remembering, exactly.
The "slop" or "play" in the fit of the spherical rod end and the pin on the brake pedal provides the movement to actuate the brake switch. Having the switch in your hand would make it easier to understand how it mounts and functions.
Apologies for the poor photo. Wow. does the dust show up when you take a photo!
