What turns pusher fan V177 on?
On my APB 2.7T AR I installed FMIC. Pusher fan in front of AC condensor deleted. Visco fan replaced with electric fan.
Can I just wire the new electric fan just as the V177 pusher fan was wired (i.e. use the wire)?
What conditions turn the V177 on (controlled through J293 module)?
What conditions turn the V177 off?
I assume engine coolant temp mainly. Passenger side V7 fan comes on with A/C on (plus engine temp?)

The larger electric fan turns on with temp and/or when the AC is turned on.
The smaller pusher fan only comes on when the AC is turned on. It may come on in extreme engine temp situations but I'm not sure.

Found this and modified the way I understand it. Would that work? Means the brown/green striped wire in PS reservoir area is switching to ground when coolant temp reaches 95 c AND when AC is on.
