Group the wires for each plug together and trim each group to an even length, then strip 4mm
from the insulation of each wire and fit the appropriate connector type to each wire:
male
spade connectors for a
female
connector body and
female
spade connectors for a
male
connector body. References to
male
or
female
will mean the connector body.
Hold the connector body in the correct orientation and insert each spade connector from the
rear of the connector body: push into place until a solid click is felt – this indicates that the
spade connector is correctly seated in the connector body.
If a spade connector is not seated correctly it may be forced back and out of the connector
body when the 2 halves are joined, so double check that each spade connector is fully seated.
The connector pin assignment shown below will be referred to again when the other side of
each connector is fitted in the

You will have used one half of each connector by now. Because you will not be using the
other halves until the
Post-Paint>Fuselage>Install electrical wiring
task, store the remaining
connector parts in the plastic boxes that they came in until you need them. This simple action
will make your life much easier when wiring the rest of the aircraft so do it now: put all the
boxes into a plastic bag, label it clearly and put it aside where you can easily find it later.
Fit the noise suppression filter into the power wire from the Avionics busbar to the VHF radio
(use male and female spade connectors) and zip tie the filter to the loom.
