The Stromberg Carlson Electric Trailer Jack # JET-5000 that you referenced does come ready to easily be wired to your trailer's wiring, but it does not have a 7-way.

You can either power the jack through the accessory circuit on the 7-way or via an auxiliary battery installed on the trailer.

If you decide to power the jack through the accessory circuit, it is advisable to use a jack whose capacity greatly exceeds the tongue weight of your fully loaded horse trailer. If the jack is working very hard to lift the trailer, the wire that carries the accessory circuit can overheat. To provide plenty of wiggle room, I would say that if the capacity of the jack exceeds the actual fully loaded tongue weight of the trailer by 50 percent, installing the jack using the accessory circuit would be acceptable. I have linked you to an FAQ article that discusses exactly how to determine your trailer tongue weight.

If the tongue weight of the trailer is greater than 50 percent of the jack capacity, you would be better served by installing an auxiliary 12-volt battery on the trailer. The accessory circuit from the 7-way can be connected to the positive terminal of the auxiliary battery in order to help maintain the battery. Keep in mind that the circuit is not capable of charging a fully depleted battery. If the battery is fully depleted, you can charge the battery using shore power and a battery charger like part # CTEK56353.
