FiTech EFI system

I’m helping a friend to make his engine run with a fitech system. Bought an msd pro billet dist including an adjustable rotor. No go, had it setup per instruction.
Not a sign to run.
Replaced the dist to a mopar orange box and not have the ignition controlled by fitech.
From the orange box there’s a wire to the negative post on the coil and likewise the blue wire from the throotlebody. Is this accurate?
Many thanks in advance.

Lets clarify. What Fitech system do you have and do you have the wiring diagram/connections for it? And it sounds like you started out wanting the fitech to control timing and now going to go back to fuel only?
