If anyone installed a autometer electronic fuel pressure gauge i need some help. The instructions say to drill a 1" hole in the firewall so you can put in a grommet and run the wires through. Does anyone have any pictures of where they drilled the hole or ran the wires? My dad started drilling a hole just to the right of the gas pedal with a small bit, but he was having a hard time going through. Also he was worried about hitting something important. Any pictures or advice would help alot.
