Before anyone gets too excited and orders this pump....

I'm just checking whether it's like the BMW E90 (on onwards, I guess) pumps that are CAN Bus controlled, or whether it's PWM.

The connection is a 3-pin plug, with a +12v & 2x ECU connections. Normally you'd think that CAN requires 2x signal buses, to obviously flip between logic level and GND, simultaneously, to generate a toggle function. Bearing in mind that one of the connections needs to be a GND, that only leaves one pin for (presumably) speed control.

Will report back once I've got my mate to clarify. In the meantime I've cancelled my order with BMW.
