Does anyone know of a large, single, brushless pusher fan in an OEM application?

if you can access the three motor wires, swap two of them and it will reverse the direction of the fan.

Good stuff! Shows that the Mazda/Mitsu controller will support BOTH fan outlets. The amp readings were surprisingly low.
