What is minimum electrical required to start my car?
OK LISTEN UP
74 's had the "deadly" "seat belt interlock." Look around under the hood for a box that resembles a horn relay that has a RED RESET button. Try resetting that and see if the key cranks it.
NOTICE I see the box in the photo, the red reset is down there below your ignition box. To bypass that permanently, find the two large yellow wires going to it, and splice them together
Later you will want to bypass it, but DON'T WORRY about it for now
You likely aware that this is your starter relay. If the car won't crank with the key, make certain the transmission is not in gear, and short the two large exposed terminals with a screwdriver, it should crank right over
Below:
Did you get a multimeter or test lamp? See the terminals on the ballast towards the left, the upper and lower are jumpered together. This is the power TO the resistor/ ignition FROM the ignition switch. Those two terminals should have "same as battery" when the key is in the "run" position. IF THEY DO NOT jumper them to a battery source, jumper the starter relay and see if you have spark out of the coil
