You can by a mechanical switch conversion kit ready made from Dwight Heinmuller or the hydraulic version from the Pacific Northwest Packard region and maybe Kanter too. Those will plug in but are a bit more expensive as you are paying for the convenience. I personally like the mechanical as it eliminates the issue of silicone fluid for those who like to use silicone but that kit is a bit more involved to install. A lot of purists don't like to see that conversion because of the somewhat visible bracket needed to hold the switch.

The hydraulic conversion is a very simple electrical circuit and all components are hidden. You can get a kit or buy a relay & socket from ebay for around $10 and with some wire and terminals, make your own. The brake switch is available at Napa or about any parts store for another $10 or $15. You can splice into the existing wiring directly or use .156 diameter bullet connectors to mate with the Packard 3 terminal brake switch plug and to connect to the new hydraulic brake switch.

I have info on the mechanical switch needed for that conversion but 55 and 56 brackets are different due to the shape and location of the pedal arms. I don't have the 55 dimensions so Dwight's kit would be the easy way to go unless you wanted to experiment.
