How to install a 3-Point Harness

This is the install guide for a 3 Point Sabelt Harness with a special thanks to "Kastle". If you have any questions or comments, please feel free to email me and ask and I will answer as best I can.
We will start off in the back seat. This is a photo of one of the plastic seat rail covers. This one is on the driver's side, on the back end of the right side seat rail, against the transmission tunnel. It needs to be removed in order to access one of the mount points for the harness.
This is a better picture of that trim piece, showing the clip that holds it in place.
With that cover removed, you can access the seat rail bolt behind it. This bolt needs to be removed and it is replaced with one of the O ring topped bolts supplied with the harness.
Repeat the removal of the plastic cover, the removal of the bolt, and the insertion of the O ring topped bolt for the passenger side.
If you pull back the carpet around where the stock shoulder belts meet the floor, you can gain access to the stock mounting point for the seat belt.
And there it is! There is a small bracket the stock belt runs through, which is then bolted to the car body.
With the carpet all pulled back, you can simply push the stock belt out of the way and clip the harness anchor to the stock seat belt bracket. It is not easy, but with a little work it will fit. By not removing the stock shoulder belts, you keep the DOT legal stock seatbelts in the car. Repeat this process of pulling up the carpet and clipping in the harness for the driver's side.
In order to mount the third point of the harness, you will need to remove the rear bottom seat cushion. There are only 2 bolts holding it in, so this should be easy. Undo these bolts, and the whole cushion should slide forward.
With the rear seat removed, locate where the anchors for the rear seatbelts are. Remove the bolt holding the anchor in, and you can stack the harness anchor with the stock anchor, and bolt the whole assembly down. Do this for the passenger side, and repeat for the driver's side.
The driver's side bolted down. By using this method, you again keep the DOT approved belts functional in the vehicle. With both sides done, reinstall the rear seat cushion.

And finally, the driver's side finished.
