Number of holes in firewall for Holley Sniper EFI

[TMartinLVNV]

I am drilling the holes in my firewall for the wiring harness pass through. The Chassis Wiring Harness guide said to drill 3 holes for EFI applications. I will be using the Holley Sniper system. As I was about to start drilling out the 1.25" holes, a voice in the back of my head said that maybe three holes are only needed for the Coyote install.

So, for my application, is it 2 or 3 holes?

I only pulled two wires and the handheld through the firewall for the sniper, but I used three holes for all the harnesses.

Ok, thanks guys. I will go and drill one more.

I don't have any holes in the firewall, not a good look. I brought all the wires around the ends of the firewall, and kept them under the edge of the firewall which was moved forward 1 1/2"

I like everything about that picture. The linkage, the plate with the swirls, looks great and clean.
