MAP sensor trick?

I bought my car a couple years ago and i noticed the map sensor is all tee’d of and basicly running to itself. Its not really running to anything.Now that im gonna be running boost im probably gonna need it hooked up right.does anyone have a diagram. I have a b16 swapped in so my diagram on my hood doent really help. I know pics would help but i have no batteries. does anyone know what im talking about? theres nothing running to the intake at all from the sensor. help

This is the vac diagram for a right hand drive b16. Hope it helps

nothing is attached

nevermind
