This works on ALL EF models (should work on RHD as well). Replaces either the coin holder or the blank plate under the fresh air switch under the left vent.
UPDATE: Have created a left cup holder specifically for the wagons because their seat sits up higher. This new version gives another ~1 inch of clearance.
