Howdy All

I'm being lazy and avoiding to spend a lot of time under the dash looking for a power source that provides 12 Volts (+) when the key is both
“ON” and “CRANKING” for my Main relay on my Edle EFI on my 56 Chevy.

Edelbrock Tech stated that I can't connect to the + side terminal of the coil like it has been for a year. Has anyone done this and can just point the best place to connect

It's not always exciting to be Polish

A 56 Chevy has 2 ignition terminals on the switch. Neither is hot in start and run. You have to connect BOTH ign1 and ign2 terminals together for power to the EFI. You should eliminate the ballast resistor anyway, so you don't need a bypass for the ballast, which is the purpose of 2 ign terminals.

There is no other place to get 12 volts in crank and run. Just Y off both ign terminals with a larger wire instead of the original 18 gauge wires, and go to the EFI relay and to the coil. There's no reason you couldn't connect to the coil, IF the wire gauge is large enough. The reason they don't want you to do it is the stock wires are too small, especially if you have a high output coil.

If all you want to run off the coil is a relay, the stock coil wiring is heavy enough. With your upgraded wiring you will definitely be good to go.
