Are you swapping to a dual res master? If so, the Mustang will work, as well as one from a 68-72 F100. They might even be the same part, check it out at your favorite parts house... The thing to check for is the pushrod length. I do not know about the Mustang rod, but you will need to cut about an 1" or so off of the F100 rod.

It is a pressure switch.
It will be the same switch that came on the '66. All you need to do is get a "T" that will fit it and cut the line where you want it, then double flare it with a couple of fittings the same size as the switch.

Not sure about the Mustang rod length. Went with 76 truck upgrade and used 1/2 alum stock as spacer between the master cylinder and the firewall. Cut them about 2-3 " long and drilled the 2 holes for the bolts. Found the alum has nec. strength, and easy to drill the mounting holes.
Understand swapping to switch is better way to go. I did not know any better at the time and kept the original pressure switch for the brake lights. Got a 'T' fitting from Napa parts, the p/n is 7900. Drilled out the center female outlet and tapped with same thread as the pressure switch. Took about 20 min. if have all the tools beforehand. Works great.
