Just did my my drivers seat as well.
European version, it only had one electric connector (instead of two as mentioned here). My seat also had a pin which is placed in a hole just before the rear bolt on right side, you see it on the picture. Helps positioning the rails correctly, couldn't remember it being mentioned here somewhere.
Front right bolt didn't want to come in, had to remove seat again (front left was already in) to clean the hole. What I did: mount the screw until it blocked. Spray some APC (all purpose cleaner) to the bolt, remove it again, clean bolt and hole, and repeat. After few iterations it wanted to go in at last.
My learnings:
Result: small scratch on the carbon tub (err, two that is, so some polishing to be done) but much better seating position!

My learnings:
- first try screwing in all the bolts with the seat still out. This will learn whether one of them is blocked by dirt, and allows cleaning - avoids issues when the seat is in
- do front bolts first. Difficult to reach, but doable: put seat all the way back, pull the lever (to move seat) up then I managed to do front-left. Then sit on the seat, if needed push the seat + yourself backwards to align hole in rails with hole in carbon tub, then pull lever up, install screw.
- luckily I have a spider, with roof open the seat comes out and goes in again easily. Probably a bitch to do this in a coupe.
