Underside of my 2017 Tacoma

I did a Google looking for a diagram that identifies what's what under my 2017 Tacoma. It's an SR with 4-cylinder engine. Turned up absolutely nothing useful, just some cool shots of Tacomas and a few showing muddy skid plates.

I'd like to know, so I wonder if anyone has a diagram?

And in the interest of shortening my learning curve, what are the tubes in the photo below? Do they get hot or can a wire from the rear to the battery be zip-tied to them or their brackets?

A diagram of the I-4 engine would also be appreciated. Also all the cables and
whatnot routed under the seats.

 

If you follow those lines to see where they start and end, you should be able to figure out what they are.

But none of them should get hot.

 

Looks like brake lines or fuel lines. you could zip a wire to them if you wanted. I personally would run a wire in the frame instead.
