It's your design my friend so I will follow your advice and order the GM sensor from you if you stock them?
I expect the fan to arrive tomorrow sometime, can I wire it temporarily just to check it works ok?
Any thoughts on getting the one 12v LED working on my dashboard?
I have reviewed my present wiring and reckon I just need a simple driver circuit that gets a signal from your controller to trigger 12v, I need some techie help here though.
The other LED will get its feed from the trinary switch, indicating fan high speed on via demand from AC. .
