I'm looking to connect a blue wire from my brake controller to a constant hot wire near the spare tire. Is there such a wire available?

Uh, any wire has to be fused, especially one not factory routed and running the length of the vehicle. It's not just about the load it's expected to pull under normal conditions, it's to prevent a fire in the event of a short due to chafing or other thingsI don't want to run the full length
of the vehicle for the blue wire which is 12 awg and doesn't need to be fused.

To be safe, you are correct, it should be fused, but if I follow the wiring diagram as per Redarc, it doesn't have to be fused.Uh, any wire has to be fused, especially one not factory routed and running the length of the vehicle.

There isn't such a wire, and if there was, it almost certainly wouldn't be sized or fused adequately for a trailer.To be safe, you are correct, it should be fused, but if I follow the wiring diagram as per Redarc, it doesn't have to be fused.

I'm still hoping someone could answer the question, "is there a constant 12v wire near the spare tire:?
There likely is a constant 12v wire available at the rear of the 80. Probably on the taillight harnesses. I don’t have an EWD handy to find the wire. I would not get your 7 pin Black power source from tapping an existing fused small gauge circuit though.I should be more precise about what I am trying to accomplish. I am installing a brake controller under the dash, and I am converting a 4 pin to a 7 pin trailer harness. The blue wire is coming from the Redarc all the way back to the brake controller output of the 7 pin, the 7 pin also needs a 12 constant. Rather then running the 12 v constant from the battery up front, is there a 12v constant near the spare tire to connect to the 7 pin? The arrow wire is what I'm looking for near the spare tire.
