I recently replaced my Master cylinder on my 72 and this switch doesn't work in it. The new switch is a single pole that goes to ground when closed so I hooked up the wire coming in and taped up the ground going out. This is a two pin switch that might meet someones needs. The reason it does not work on my new master cylinder is that the plastic pin that goes into the MC is slightly larger and does not fit. I understand these are expensive and hard to get. This one is free to a good home. I don't have paypal or venmo so shipping is included. Click to view attachment
