There will be an arrow on the shroud that points to the right on ours. It was spinning to the left. P.O. had not only flipped the plug but had switched the wires on the fan side of the plug. thankfully there is a #1 and #2 on both plugs to confirm correct wire and connector engagement. I made the correct adjustments so that another mechanic that is not as sharp as I will be able to re-connect.
