Suggest you read the complete document or look at the diagram. Two pairs. Red and black for "unswitched" power, and yellow and green for "switched" power. Would not recommend using power from one and ground from the other. Might work, but why not follow the manual? Page 36 in the link Dan provided has what you are looking for.
