Here's a rudimentary question...I need to run some wiring from the hot side of the contactor on one of my batteries through the firewall in order to provide backup power for my EFIS.
How to drill through the firewall? Is it as as easy as just drilling a hole and putting a passthrough with silicone grommet and Firestop, or are there other considerations I'm missing?
