Here
is the carb heat cable as it exits the firewall and bends towards the carb
heat box. It isn't connected to the bellcrank arm yet.
I
fabricated a bracket for the carb heat push-pull knob directly under the
pilot-side air vent.
This shows the engine sensor wires coming through a
plastic grommet in the firewall and then a yellow adel clamp holds them
securely. These wires will be fastened to connectors that will plug
into the EFIS.
This is the forward side of the firewall showing the
wires going through. This side will be covered in red RTV and
possibly some fireshield.
