Fuel flow pin out

[Ron_B]

On page 6-15, the manual shows the fuel flow pin out. Pin # 14, (yellow) is fuel flow input 1 , pin # 15 , (red) is +12 volt aux and pin # 19 , (white/black) is fuel flow input 2.
With the EMS harness pins 14 and 15 are twisted with a black wire connected to pin 13 (ground). The fuel flow transducer has three wires, a black, red and yellow.
I assume we use the three twisted wires ,(red and yellow and black) and connect them respectively to the fuel flow transducer. The white/ black wire, pin #19 would be used if we had two fuel flow transducers?
They way page 6-15 reads to me , we would use pins 14, 15 and 19 but I don't think that is what is needed.

Pins 13,14,15 should be bundled in a black, yellow, red bundle. These hook right to the fuel flow transducer.

You'd only use pin 19 if you had a return flow transducer.

The fuel flow sensor ("Red Cube" FT-60) I received with my sensor package has red, white and black wires as opposed to the red, yellow and black on the harness. I assume the yellow connects to the white and the red and black match with the red and black from the harness.

This is correct.
