1995 BMW 325i Engine M50TU Question: 2 Pin Wiring Connector Location on Intake Side?

See Photos. 2 Electrical 2 Pin Connectors I Labeled "Intake" with Masking Tape.

I just installed a New Starter which required removing the Intake Manifold for access.
I took many photos and labeled various connections for reassembly.

The Shorter "Right Side 2 Pin Wiring Connector" only reaches the underside of the Manifold for the Air Temperature Sensor.

The Longer "Left Side 2 Pin Wiring Connector" is the same size But I Cannot Find Any Place It Plugs In....???

Is it possible it was never used / plugged anywhere and I mistakenly Labeled it "Intake"...?

The Female 2 Pin Silver Surfaces (See Comparison Photo) are Green Corroded on the mystery Left Side Connector versus the Right Side that reaches the Manifold for the Air Temperature Sensor.

Any assistance would be Greatly Appreciated.
Thank you.
