You should be able follow those two empty wires to your 7 pin. You can wire in but it may not allow for your trailer to signal the brakes until an actual trailer is connected in the pin receiver in the bumper.

Hope this helps
it's the factory brake controller. 7 pin. but the manual, as noted above, says 2 wires are run to the fuse box, but not connected.
