I have a 1991 gen III K case 700r4.... no pressure ports on the passenger side. The most common recommendation is to run 12v power from the brake light switch. Okay, no problem. My switch is a normally open pressure switch in line from the master cylinder. Wiring to the hot side of the switch will give me 12 volts all the time.... good. Stepping on the brake pedal changes nothing, still get +12v. There is nothing in my setup that will drop out power with the brake pedal unless I go thru a relay. Again, no problem. It appears to me that an easier solution is to just run switch power thru a switch. What say you?
