Looks great once your done, just don't believe the instructions...
This is a great add on for your Buick Envision. Give the look of a more expensive vehicle.
One thing that you should be aware of, the instructions. This product would have gotten 5 stars but it looses one for bad instructions. The connection procedure is totally incorrect. Should you purchase these illuminated sill plates forget trying to power them from the Body Control Module. The pin the instructions the ask you to connect to do not exist. It is a blank pin location with no connection.
Instead, drop the panel under the passenger and driver side dash, find the courtesy light and tap into that on each side.
If you do that they will work perfectly and you will not be required to remove any panels from the console or fiddle around with the BCM. And the illuminated sills will dim slowly with the interior lights. No loss in functionality, a much easier installation and a great look.
