In my experience, the manual is almost useless. Here's a video with the location:
The front SAM is under the curved black plastic cover and getting to it is tricky. You have remove the auxiliary battery, undo the two Torx screws (E8, I think), peel back the flooring to expose the three plastic bolts and one Torx screw. When they are removed, you can lift the compartment cover enough to release the SAM and its cover and unclip the connectors.

Part number

Lift the compartment, slide out and remove curved black cover, then unclip the connectors by squeezing the ends on the front two sets and pushing on the tab on the top of the rear two and sliding the arm forward to release the pins for the rear two.

Near console

Torx screw

Under where the battery is

At rear
