No Spark help

My slant 6 was already wired with an electric choke, but the 318 I bought still had the resistor for the choke, that's the only reason it was carried over. Could I keep that as is and use it to go to the electric choke? Right now it would have my dark blue wire connected to it (hot wire), but then I have a brown wire that runs back to the bulkhead connected to the other side of it. I'm not %100 what the brown wire feeds until I can get a more accurate diagram. But my thought was keep the blue there and make a jumper to my electric choke, is that ok to do?
Not sure what you're saying about the choke resistors. The '73 diagram doesn't show any difference in wiring for a six vs an 8.
It only needs, and only should get power when the engine is running. In fact all it does is speed up the choke opening - my recollection is there still was a mechanical (bimetal coil) choke on the intake. Maybe I'm wrong it its an electric only deal. Regardless, it only gets power when the engine is running. There should be a control switch then the resistor and then connects to the choke heater.

Blue wires are usually from ignition 1(run).
Brown wire to the ballast resistor is usually from ignition 2 (start).
For '73 and sounds like '74 as well, the coil feed wire is also brown.

In Start - brown to the ballast should be battery voltage.
In run - blue to the ballast should be system voltage (either battery or alternator - whichever is higher)
