How can i convert a switch box thats WIRED for four pumps over to two pumps without having to add wires internally.

u don't add anything. all u do is disconnect the 2 wires that were for the 2 pumps no longer used..then just have to jump the wire for the front pump that the other front pump us to be wired too..if u bought the car and it had 4 pumps and now 2...its just best to re wire the switches again...

yeah just double your front pumps&rear pumps for instance connect your front right pump to your front left pump wires & connect your right rear pump to your leftrear pump wires .
