Attach your factory seat belt buckle to your new seat bracket (if applicable): you may need a new bolt and a nut to install the buckle.
Maneuver your new seat into your vehicle: again, be careful to avoid scratching your car with the seat bracket.
Plug in electrical connectors: locate the electrical connectors that you unplugged from the factory seat, and connect them to your new seat. If your new seat can’t accommodate any of these connectors, leave them unplugged.
Line up the seat bracket: locate the four holes from which you removed the four bolts holding the factory seat in place and line them up with the four holes at the corners of the seat bracket of your new seat.
Bolt down the seat: install the original factory bolts in the reverse order of removal. If you’re using sliders, take advantage of them! Slide the seat back to install the front bolts, and then slide it forward to install the rears. Careful not to over tighten them!
Check your seating position: make sure that you can position the seat in a way that’s comfortable for you. If it’s not possible, pull the seat out and try mounting the seat using different holes on the brackets and sliders.
