Carburetor, MSD, Holley Sniper EFI questions

I have had my Sniper a couple years. Big learning curve for me, early issues but pretty happy with it as I learn it. Still learning it, just enabled the timing control this year. There is a Holley Sniper owners and tech page on Facebook, lot of info there. I would suggest to run it without the timing control At first to eliminate any issues there. Also put shielding around all the wires. EFI is a big issue with them and it’s a lot easier putting it on outside the car versus once installed. I don’t have the MSD 6a, just a coil with the supplied coil driver. I kept the ballast resistor but ditched the orange box. Recommend relay for pink wire, think through how to connect it as it needs to be powered in both start and run. My sniper has its wires come off the back, plenty to reach the firewall.
