QUestion about hooking up edelbrock carb... Wire to electric choke?

That's why I used the blue wiper feed. If it shorts and fails the only thing I loose is the wipers and no rain driving for me! The breaker in the switch will reset once you remove the short by disconnecting the choke! As well it is easy to hide for those looking for authenticity!
There's a single wire from ignition switch to feed 3 "hot at switch on" branch circuits through the fuse box. Heater blower, wiper, radio, etc... So basically ( beyond the ignition switch, you're on the black wire instead of the blue wire that most others are using.
I'm not sure your method will prevent the madelectrical meltdown or ignition switch failure either.
My knowing of the load generated by crusty worn wiper pivots does put your method a tick above those others previously suggested ( If our thread starter is willing to forfeit one thing for another ).
For any 67 model owners that might be following along... The circuit breaker mentioned above is built inside your wiper switch so don't even consider this.
