I don't have the engine ready to fire yet, I was just testing the wiring off the battery.

Where is the early type switch mounted ? It needs to be mounted as the early type switch on the transmission. That switch is normally open. Depressing the pedal then closes the switch and therefore the circuit.
The 30-31 switch mounted on the crossmember is normally closed and releasing the pedal on that type switch opens the circuit.

I have it mounted in the correct spot, I'm using an aftermarket battery box with hydraulic brakes.
