Sounds like a great update Tor

Im installing your original harness with an switch from Aliexpress and a relay, as described earlier, but is it possible to get 12v and GND from the harness, so I don't have to wire it elsewhere..?

It is possible, but I would not recommend it unless your really know what you are doing. And you absolutely must seperate the circiut connected to power from the climate control harness cables. I have never seen a automobile switch with lights that seperates 12+ from output. So you either need a relay or optocupler.

Another issue is that some of the +ve cables to the harness is live even if the car is OFF so that tapping into these may cause drain.


The easiest access to 12v is from the 12v outlet. It is really easy and simple. Or you could just wait until I am launching my switch kit...

Thank you very much for creating this kit. I ordered one on your site.

We are one week further, still no response... Is the site still active? Is Tor still active?

Update June 4th: Tor is still Active, and he has send me the heater kit. I will hopefully recieve it next week.

Update June 10th: received the heater controller kit yesterday. Really nice package, easy to install. Hopefully this winter it will increase my range enough to make my 84 km commute easier. Thanks Tor.
