[urq] : A/C - fan always on? Hybrid application?

[Martin Pajak]

Do you have it set up so that the A/C controls the fan in stock way?
Is the fan still relayed in the fusebox with stock relay?
It should then still get the same signal from the A/C side and function
the way it did prior to conversion...

Do you have an updated schematic for your "new" wiring?
That's a good idea if doing harness swaps to keep on top of it few years
later when you don't remember what the "red/green" wire did anymore.. :)
I did that on my 3B conversion and saves me ton of time now when trying to
find answers.

Cheers
Martin
