FFDM-1 in the aircraft as outlined below (see sheet one ). Otherwise, omit this step.
a) Connect the connector to the FFDM-I.
b) Install the FFDM-1 under the instrument panel using two tie wraps on each end of the module to
support it to a wire bundle or bracket.
c) Route and connect the 3' red power lead to the 12 or 24 volt bus via a 1 amp fuse.
d) Route and connect the 3' black ground lead to the same ground used for the EDM-760(),with Fuel
Flow option.
e) Route and connect the 6' red, black and white leads marked "Feed" to the flow transducer installed
in the fuel line from the fuel pump to the carburetor.
f) Route and connect the 6' red, black and white leads marked "Return" to the flow transducer
installed in the return fuel line from the carburetor to the fuel tank.
g) Connect the red, black and white leads to the same color 6' leads from the EDM-760(),with Fuel

so they do not obstruct the freedom of travel of any controls.
