Wiring question

quick question about my 12v lead for my trailer wiring. i installed my hitch and 4 pin flat wiring a few weeks ago on my 2013 taco 2.7 prerunner and i want to install the adapter to make it a 7 pin round.

I just bought a 4 pin flat to a 7 pin round adapter and the 30amp breaker. I was just wondering how i run my 12v power lead to the battery and how i connect it to the battery.

The rest (ground, reverse lockout) i think have covered.

I don't have a brake controller.


Thanks!

 

If I'm thinking right all you can do is run your power wire along the frame underneath truck and hook to battery with your Breaker

 

That's pretty much what i was thinking. i am also wondering how i connect my wire to the battery
