I received my engine yesterday (finally!!) and figured I'd get the various fittings installed on the rear case today before mounting the engine tomorrow.
I quickly realized that the drawing on page 43-05 (RV-14A manual) bears little resemblance to the IO-390 configuration I received from Lycoming. For instance, the drawing shows the oil temp location immediately adjacent to the tach drive where I have a safety wired cap. The drawing also shows only a milled face adjacent to the oil filter where I have a removable red plastic cap.
I've drawn three arrows on the attached photo. I think I know what two of them are, but the third is a mystery.

- White arrow: oil temperature probe location (If so, where does it get safety wired, since Lycoming used the adjacent location to safety the oil filter?)
- Red arrow: upper oil fitting (for one of the oil cooler lines)
- Yellow arrow: a complete mystery (????)
