Yes, it is possible to wire your Stromberg Carlson Electric Trailer Jack # JET-3555 into the 7-way. There isn't much room inside of the 7-pole plug so the easiest way to power your jack from the 7-pole would be to wire it to the 12v power in your trailer's junction box.

If you follow the 7-way cable along the frame of the trailer you'll see some sort of box where the wires from the cable will run and connect to the wires for your trailer's lighting and brakes. A lot of the trailers that have come through here typically have a metal junction box like you'd see in your home with the wires just connected together using electrical wing nuts. This leaves the wires pretty much exposed to the elements and can allow the wires to get corroded and brittle.

If you have a metal junction box I highly recommend upgrading to a plastic junction box like part # 3375601101 to help protect your wiring, make wiring in new items, or troubleshooting any wiring problems easy peasy. Junction boxes like these have posts to easily separate and organize your wiring. You'll be able to run your jack's power wire directly to the box and connect it to the post that your 7-pole 12v power wire runs to.

I've attached a video below where I'll walk you through wiring in a junction box as well as our help article on trailer wiring.
