Question:

How is the Jacks power. provided? Can it be powered through the power plug on the tow vehicle? If not is sufficient cabling provided for inside 12 V battery?

The Stromberg Carlson Electric Trailer Jack # JET-5000 uses a 12 volt system. The jack will perform better by drawing power from a nearby source rather than through the 7-way wiring harness.

I would recommend you use a trailer mounted battery if possible. This jack has a 5000 lb weight capacity and has a 30 amp draw on a normal rated load.

If you prefer to use your vehicle power, this can be done by splicing into the trailer harness wiring. I have attached a photo that shows the position of the 12 volt power pin on the 7-way connector. Make sure you connect the black wire from the jack to the wire coming from the 12 volt power wire pin on the connector. I have linked you to an installation video that shows wiring to the trailer harness that plugs into the vehicle.
