The replacement assembly is wiggled into the door cavity and lined up with the mounting holes in the door. Installation is basically the reverse of removal. All 8 of the nuts and bolts are started and loosely threaded. With everything in place the new regulator and motor assembly is tightened into place. The motor wires are plugged back into the new motor (upper right photo).

The tape is removed from the window and the the window is slowly lowered onto the mounting brackets on the regulator (lower left photo). With the window seated squarely on the brackets, the bolts are reinstalled and tightened.
