An installation apparatus for mounting a garnish on a vehicle can include a jig, a tool and a controller. The jig can be placed on a predetermined portion of the flange and in a predetermined orientation relative to the flange. The jig can orient the tool in a predetermined orientation relative to the garnish when the jig is placed on the vehicle and the garnish is positioned adjacent to the vehicle. The controller can be configured to indicate an install complete condition based on force data and tool proximity data, where the force data is indicative of a force applied by the tool onto the garnish while the tool installs the garnish onto the first portion, and the tool proximity data is indicative of a proximity of the tool relative to a portion of the vehicle after the tool mounts the garnish onto the vehicle.
