Ben replaced the fan clutch, fan blade, serp belt, water pump and heater core earlier this week. We found out that there is a early and late memory seat harness for e32 and e34's, the changeover date is early 93 but I forgot which month. Apparently you can swap the harnesses and all memory functions will still work including the power tilt wheel. For now the '89 750i drivers seat purchased from TCD is wired up just to slide back and forth until I have time to pull a e32 harness from a yard.
