... Cannot find a Furukawa QLW .250” male connector ....
It does not appear to exist commercially
however you CAN find a 2-way male/female set AND male & female terminals only from the same series i.e. terminals are same for the 2-way and 3-way connectors
Furukawa QLW 250
Option 1.
Buy TWO* sets of 2-way male/female connectors, remove the wires/terminals from your OEM 3-way and insert into two female 2-way shells - then make up extender cable from 2 -male 2-ways (one will only use one position/wire) and connect the three extender wires with new female terminals into original OEM 3-way shell.
For the Output connector, you will need another single male/female 2-way pair and repeat the process - simpler because you only have one pair of wires rather than all three.
* well that would be three sets altogether - one for the output and two for the stator
Option 2.
Just buy the terminals.
Make up new extender cables with male terminals at one end and female at the other;
remove the OEM 3-way shells and install onto the new extender cables;
Slip heatshrink over each of the three individual wires and mate the males to OEM harness female terminals;
Slide heatshrink over the mated connection and shrink.
Either method will preserve integrity of OEM harnesses and allow complete reversibility.
I would probably go with a hybrid of the two - use the actual 2-way complete connector set for the output harness and just go with the mated/heat-shrink option for the stator extender (predominantly because of bulk)
Note that the stator wires can go into any of the thee terminals - you do not have to track these as per original specific pin location
Obviously for the output, you need to ensure you follow the correct polarity for male and female
