To preface this - I don’t fit in the e30 comfort seats. My shoulders touch the headrest and they’re very uncomfortable
Anyway.. e90 335i front seats going into a 4 door 1988 325i. As far as I know, they will fit with some small modifications to the rails but the problem is the electronics. This car doesn’t have heated seats or electric seats or any of the switches or circuitry.
I’m assuming I just need power to the seat motor, an earth and everything else (airbag) can be disconnected?
Also I’ll be ditching the e90 seat belt mechanism due to the pre tensioner
Any guidance from someone who has put these seats in would be amazing
