Simple question

[dhillman]

Hi friends. The plug from my auxilliary coolant pump broke into pieces (the plastic part)leaving only the 2 pin connectors. One wire is black and the other is brown color. Which one is positive? Also, If the coolant pump is connected in reverse polarity, will it pump anyway through the heater core? or, it will be the same as having a closed monovalve? Please reply, wiring diagrams does not show the wires at the pump, only the ones up to the connector.

Thanks again.

The brown wire is the ground (-) connector.
