Wired the G3i ignition on the aft side of the firewall. The firewall forward side will be completed later.
I also fabricate the power cable for the VP-X and the MSD G3i unit which are both connected directly the battery pass through terminal on the firewall. I then installed both, along with the battery cable coming from the rear of the aircraft.
While on our auto store visits yesterday, I purchaed an inline fuse for the MSD. I was uncomfortable connecting it directly to the battery without fuse protection for the wire.
