I am currently fitting my racing seat, thought I share what i found: after removing the 4 screws holding the seat you will encounter only 2 different cables/plugs on the bottom of the seat: a yellow and a brown one. Brown is for seatbelt occupation (if seatbelt is plugged in or not), you can keep that if you simply transfer your seat belt, or put it somewhere hidden The yellow one for the airbag you can easily replace by a 2.2 Ohm resistor (ofc you lose the seat airbag). See picture attched, there are more cables going to the seat than rly needed, the seat uses only the described ones.
