Locate and create holes in firewall for cable pass thru.
Holes were created using knockout punches of appropriate size.
The pass through for the EFII components was made from a SS pipe flange obtained from McMaster. It was shortened and machined on the Smithy to reduce weight. The flange was then drilled for 8-32 hardware.
I received a mock up of the B & C standby alternator. The mockup was installed to verify nominal fit and clearance with the Airwolf remote oil filter adapter.
