Rotax sensor connector 881302 fuel pressure

That video shows a wing being built on a KitFox

I am going to put on my Psychic Hat (Magic Mirror?), Close my eyes, and say the Magic Words, "Romper Bomper Stomper Do ..."...

What I see is a Fuel Pressure Gauge Connector that you connect to Pins 1,2, and (3or4) of J243 of the GEA24.

Pin 1 = Ground
Pin 2 = Signal
Use Pin 3 if  your sensor's V+ =12v
Use Pin 4 if  your sensor's V+ =5v

I can't see the wire colors.
If they are Red, Black, and another color; that would be Red = V+,  Black = Ground,  and the OTHER Color = Signal

Otherwise, Brown = V+,  Blue = Ground, and Black = Signal   (Crazy, I know!, But it is the Industry Standard.)

(End of Magic Trick!)
