Well, i am trying to install my tnt setup myself that i bought used from this site. I cant figure out why the bottle heater has two white wires? Can i run straight power to it and then to a rocker switch? Plz put in your two cents, thanks.

 

Do not run a simple in-line rocker switch. That line will have anywhere from 15-20 amps being drawn on it, any that will fry and rocker switch you use. You'll need to wire in a relay. Both wires on the bottle heater are white like you said, there's no polarity. Just pick one to ground and one to put power to.

If you'll look through the sticky with all of the wiring info, there are good diagrams in there to understand how to wire a relay in as well.
