Hello everyone.

Sorry for jumping in your forum.

I have a thermo top c and I'm trying to get it to work, most ( if not all ) the info iv read about has come from this forum so I thought I would ask direct.

I am confused as to applying 12v or ground to pin 1 or pin 3.
And what is classed as old or new model.
The sticker on mine says 66724b.

The heater is from a bmw e53 x5.
I have connected it up thermo test software and can only talk to it when I select Thermo top c/z bmw.

Any help will greatly appreciated.

Andy.
