In the case of avionics that run dual power wires (supposedly to ease load in each wire), is it okay to terminate the two wires into a single connector to attach to c/b or should each have its own connector?

Thanks in advance.

No expert here but I have the same question. I have seen harnesses made by a
pro shop recently and they just run one wire and a short jumper over to the
second pin at the distal end. I'm thinking they want to reduce the load on
the pin, not so much the wire. In some cases like the GRT stuff and some
Garmin the extra pins are to accommodate separate busses and are diode
isolated from one another.

Multiple wires in to a single crimp are entirely
acceptable. See:

. . . although you probably don't need to to
to this effort to make sure that two wires get
properly inserted to equally share the wire-grip
space.
