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.

Questions: Is there a product or installation manual available for this? If not, what else is required for installation? Does it just get connected as a loop in the coolant lines? Would be for a 48 CJ2A that was not set up with a heater...

Its pretty straight forward and is just a loop system. We can also fax you over the instructions if you need us to. Mike@kaiserwills.com email us your fax number there.

Questions: I have the original 6 volt system in my CJ-3A I see since 2010 the answer to the question of do you have a 6 volt heater has been... its in development. By 2013 you replied... hope next year. Well now 5 years , Do you have a heater that works with a 6 volt system? If not, do you think you ever will and if so, please be specific when it will be available. I really have been checking for years.
Question By: George on Jan 22 2015 12:00 AM
Sorry, our supplier has not yet come up with a 6 volt version for us.
Answer By: Willys Tech on Jan 22 2015 12:00 AM
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.
Answer By: Ron on Mar 30 2017 3:14 PM
Sorry to disagree, but a resistor will lower the voltage, not raise it. An inverter is required to raise 6 volts to 12.
Answer By: Tom Johnston on Jun 18 2020 10:09 PM

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.
