I don't think this is a very good idea since the electric jack
will draw much more power that the 4-pin connector and wiring is
able to handle - to say nothing of the fuses.  Better idea is to
disconnect the electric jack wiring (isolate the jack) and use
your jumper cables from the tow vehicle battery to power the jack.
(You do have jumper cables, don't you?).  Without isolation, you
could be backfeeding the 12 v. trailer electrical system.
