cranks but won't start?

I believe that is your C105 plug .You are saying that the DG/OR from cavity 12 of connector 3 is going to this ? If so that is connector labeled C105

I will give you some things the male side wires out of the plug are feeding , so maybe you can trace them and find the male plug .
WT/OR wire is going from the male plug of the c105 to abs controller
Wire from the ac low pressure switch is going to the male plug , diagram is vague on that color
Both of your oxygen sensor wires DG/RD will feed to the missing connector also
Wt/DB from your generator is going to the plug-that would explain your no charge

I will show the wiring diagram for the low side ac switch and couple of pics of the connectors. Hopefully you can trace some of the wires above to the male connector -Good luck !!
