Couple wiring questions

[todds89]

Wrapping up the wiring on my dad's 35 Truck build and have a couple questions...

He is using a FiTech fuel injection and an MSD Digital 6AL, MSD Coil and Pro-Billet Distributor.

The ECU needs a clean 12V while cranking and while key is on.
- Will the "Orange EFI or Coil" wire provide that?

The MSD box needs a 12v keyed source.
- I was thinking to use the "Electric Choke" for this since we aren't using it

I think these are right, but just figured someone already went through this.

Appreciate the help.

I have a Holley Terminator X that also requires a clean 12v while cranking. I used a multimeter to determine that the orange EFI wire provides power while ignition is on and when cranking.

Perfect, thanks for your help!
