Put the inlet to the head at the 4 o'clock position. The the exit is either one of the exhaust fittings looped to the exhaust flange. Put plugs in all the others.
You only need a single pick up. Some would say to go in the exhaust first. I can tell you for certain after having telemetry hookup. It does not matter. The water is going through the system so fast it doesn't matter. And I live in south Florida where water temps in the upper 80s are common.
