Questions: How do you route the defrost? Do you have to cut holes in the dash or does it hang on the outside? Is there a vent for this purpose or do you have to make your own. I will be ordering one but need to plan so I can do whatever cutting I need to before paint, which is coming soon.

By 2013 you replied... hope next year. Well now 5 years , Do you have a heater that works with a 6 volt system?

For those people who want to put a 12v heater in a 6v jeep just add a resistor from 12v to 6v pretty simple to do.

Questions: I know this was asked in the past but didnt see new, is there a way to run this on 6V?
Question By: SSG.Monte on Nov 22 2014 12:00 AM
Sorry these are for 12 volt only.
Answer By: Willys Tech on Nov 24 2014 12:00 AM
you can add a resistor available at auto supply shops to drop 12 to 6 volt. I did this on an old jeep wagon when i converted it to 12V and kept original 6V heater motor. Did same for radio.
Answer By: Jack on May 2 2017 5:12 PM
you do not want to run a 12 volt electric motor on 6 volts. installing a resistor in a 6 volt system will drop voltage not step it up to 12 volts. you can replace the 12 volt motor with a 6 volt motor. just have to research the motor out. I would do it before you buy the kit.
