I'm not fond of the idea of cutting a hole through the firewall for a manifold heater. If the hole was already there, I would probably have a different opinion, but there isn't already a hole.

My car is 6V positive ground. So, I've searched for a 6V water heater for a while. I would think that a number of 6V cars are still around, and I'm surprised there doesn't seem to be a 6V solution. I've seen Arvin heaters on eBay, but I'm guessing that they are going to need lots of "tender love and care" to get them to work (because most of them are probably already worn out before they landed on eBay).

This seems to be about the smallest footprint for a heater that I've found, but it is 12V. I'm guessing that this heater is also negative ground.

Has anyone converted this heater (or a similar heater that can still be purchased new today) from 12V to 6V positive ground?
