What's the best way to replace the Cluster Voltage regulator?

This may not be relevant but some may find it useful...
The round main harness connectors are keyed so they attach only one way. As far as I know every board ever made accepts that key in the 12 o'clock position.
When an engineer draws a schematic he might rotate that connector so the key is shown at 9 o'clock or anywhere he chooses. This is not to confuse the novice. It is only to simplify the drawing so it's easier to follow. My point being... the wire locations remain relevant to the key location regardless of that keys orientation on the drawing.
i had a IVR customer with all sorts of crossed circuit issues and we messaged back and forth for nearly 2 weeks before he mentioned that he was using a schematic to wire his connector.
In the end I felt his beer drinking was the reason for his misreading the schematic and my final statement to his was "It's 5 o'clock somewhere". LOL
