- Prepped firewall for battery box installation by drilling out 3 rivets and enlarging holes to #12 - Drilled/cut/deburred the 2" hole for the TG-10 Cabin Heat selector valve. Ended up using a cutoff wheel in the dremel tool to complete the cut. - Drilled/deburred the holes for the throttle, mixture and prop per drawing OP-33. - Drilled/deburred a 3/4" hole in the upper central firewall that will be the pass through for the electrical wiring. - Drilled out rivets for the VA-168 sender mount and the Dynon Manifold Pressure Sensor. - Drilled and installed nutplates for the Primary Power System (PPS).
I also opened up the D37F connector harness for the EMS and pulled the unused pins/wires. That was about half of the wires present. The cheap plastic pin puller pretty much died, so I need to buy a metal one.
I also spent many hours over the weekend reviewing wiring diagrams and sizing the 3/4" hole.
