Very high quality harness w/ the added feature of being a click in/click out set. Once installed literally a one minute clip in/clip out
Here's an overview
The system uses two of the oem seat belt receptacles- one in the front, one in the rear, both towards the middle of the car. You must install two mounts/clips- one in the front, one in the rear- these once mounted, stay in the vehicle. The both mount to oe seat belt mounting locations.
Lets get started, we'll start w/ the front. Your going to mount the front clip where the lower front seat belt fastens. To do this we have to get some "stuff" out of the way. You'll need to remove the lower center pillar trim piece. Start by unclipping the front door sill piece that overlaps it, same in the rear- you just need to pull those piece up enough to get the center piece out.
There is a fastener in the rear of the center pillar that is removed. The piece simply pull out, go slow don't want to break any of the plastic.
With the lower center pillar piece out you'll have to pull up the edge of the carpet a little bit to expose the bolt- to do this you need to unfasten a clip in the front and rear (pic showing the front one). Now you can see the bolt- it's a 14mm bolt- remove it.
