I have a 2014 3921. The power wire is not hooked up from the factory. The trailer harness has 2 extra wires in the harness that are folded back in the harness back by the trailer connector. I believe one is orange and one is black. Both wires drop out of the harness under the dash on the left side of the steering column. There are extra connections at the auxiliary fuse box to hook up to power supply. Mine had plenty of wire to reach the trailer connector and the fuse box. Hope this helps. I'm sure many others have done the same thing.

Yes, I used the orange wire. Put a terminal on the wire and plugged it into the aux fuse box with a 20 amp fuse. Locate the orange wire at the back by the trailer connector. It should connect to the center terminal in the connector. There should only be one unused terminal available to hook the wire to.

It is folded back inside of the wire loom

On mine, the center is the reverse light and trailer surge brake lockout pin. +12V is one blade of the ring, the one immediately clockwise of the index in the truck socket.
The OP should verify which one it is, unless of course there is only one that's not connected. But then, the trailer plug must match, too.

The "7-Way RV Standard" shown at this link is the correct pin assignment to use.

KanzKran is correct about the power terminal.
I believe the center pin on the towed vehicle is the power terminal on the 6 pin connector.
Look up the post (what and where are extra wires from rear) on this forum for a good description from another that did the same thing.

I suspect your canyon star manual has a pin diagram. My BSS does and it shows black (#4) for the power pin. The center pin is for backup.

What’s odd is that both 7-way RV-style connector schemes have the same function assigned to each pole, but the wire colors are different between utility/cargo trailers and RV trailers, and tow vehicles too for that matter. At least according to the e-trailer page linked to above.
7-way heavy duty (round pin) industrial/commercial connectors have a different pin assignment, though, so no confusion there.
