There are 5 connectors on a new wheel assembly, but the connectors vary a little for the left wheel assembly vs the right wheel assembly. These images are specific to the right wheel assembly. See the next step for the left wheel assembly images.

Locate the 5 connectors on the vacuum. Note the direction all plugs are plugged in so the connectors can be reconnected the same way.

Also note in the image, there is a dab of glue (bluish green stuff on each connector) helping to hold the connectors together. It's a good idea to use an adhesive when changing the wheel assembly.

Use care when disconnecting and reconnecting the connectors as these can be difficult to get apart.
