plug and play not working

Not sure if I can see ignition supply to coil +. Coil connector picture is not in view.
Do not ground the black and yellow wire!! The ignition module drives that. Just connect yellow to black, insulate. Follow schematic.
If you want a ground, ground distributor body. That makes good ground when adjusting timing, when hold down bolt is loose.
Where is your coil to cap plug wire? Vacuum hose to ported carb port and vacuum advance?
