I had to order the exact same Control three years ago-----It came in complete---Just pop the old control off and put the new one in-----You have changed---You send the sensor panel---I had to take the old sensor panel out and pray I did not break any of the 4 posts that hold the sensor panel into the outer Plastic Panel. Takes longer and more caution, But I was able to complete it and snapped the control back into the door. You need to send this control panel out ready to take off the old and pop in the new.
