Use care on reassembly not to catch any cables under the mainboard. I circled the ones that gave me problems.

On the press in connectors (earlier circled in yellow) I used soft-tipped tweezers to slowly wiggle them back into place. Be sure all connectors are fully seated!

The flip-up levers on the board need to be flipped up to insert the cables. Make sure the cables are fully seated before pushing the levers back down to secure the cables.

The main sensor connector (circled blue earlier) will snap down with some force into the mainboard. Make sure it is well aligned with the connector to prevent damage to either part.

The top right connector with the colored wires (circled purple earlier) will snap straight down into the connector with some force once it's aligned. It does not plug in from the side.
