There's also a module available too, check FB groups... If i recall, Paul Rogers?, runs it
I worked with Larry who makes the module to verify what wire was needed to tap into on the Gen2. I also did the video of installing it, but other than that, I don't have anything to do with it. Sounds like he isn't making them currently due to health reasons.
It works perfect though. I use it all the time in the winter and at the dunes.
Thanks,
Paul
