Take a good look at actuator, in your hand.
Does it suggest how it's mounted?
Remove the door panel, the paper cover and anything that is in the way.
inside the panel between the inner and out door panels is where the actuator is mounted.
Remove the mounting hardware, remove the power connector, remove the old actuator by unhooking the rod to door lock assembly.
Reverse the whole removal job to reinstall.
Test out before putting door panel back on.
Some of it is not so easy to do.
Good luck.
