assuming by electrical you mean the electric choke? i think you can take a +12v lead off the coil that is only on when the ignition is on. Make sure you check the voltage and get the right one. the only other vacuum line goes from the carb to the vacuum advance on top of the distributor.

fuel should be pretty easy. Unless you took the fuel pump off, just connect the line you have hanging to the Weber.
