That would make senseCan’t remember without looking at it but I think there is a y cable at the factory intake manifold pressure sensor.
I wish the shop would’ve done thatI like using blue tape on each end of the connector with same number so there is no question what goes with what. Or simply writing what the item goes to.
Yes I think your picture is the correct harness. Is it not plugged in?
You can download the Edge manual here. The boost comes from the MAP sensor and the connector changes every year.
