What is a direct wire heater, you ask?

It is a 12-volt car heater that gets wired directly to your vehicle's battery--and, as a result of that direct wiring, it can produce a level of heat in your car that will do more than just defrost and take the edge off the cold.

Can I install it myself?

A directly-wired portable car heater is a fairly simple, do-it-yourself way to make your ride more comfortable, warm, and safe. The basic installation steps are as follows (and full DIY instructions come with the device, of course):

* Mount heater in desired location
* Run wires through vehicle firewall
* Set heater in the "Off" position
* Connect BLACK wire to the negative (-) battery terminal
* Connect RED wire to the positive (+) battery terminal

How does a direct-wired 12-volt auto heater work?

Like your car's original heater, It draws its heat from the hot water in your car's cooling system. Unlike a built-in car heater, it is compact and easy to install. Whereas the cigarette lighter plugin might be considered a bare-bones emergency fix, a direct wire portable car heater like the recommendation above comes closer to being a replacement solution.
