manual cluster and manual steering wheel are not essential. The cars miles are stored in the cluster not ecu, so its probably a bad ideal to change it. another option is to replace the overlay from a manual onto your auto, though the odometer openings are missaligned slightly. or just leave it auto.Curran, what would happen if you stuck with the auto gauge cluster (besides looking like a d*ck with the gear selector indicators on your manual car)? I'm still gathering parts since this swap will be from auto to AR5 and I've only had the car for a week, so I'm just wrapping my head around what is ESSENTIAL and what just looks better (like the manual steering wheel). I've located a salvage yard within driving distance that has all of the interior bits I could need, so I'm just building my shopping list for IS based parts. Thanks for any help.
obd2 will continue to work, i dont believe the vin is stored in the ecu or even labled on the outside.I am still concerned that the new manual ECU will not scan via OBD2 port and register the correct VIN for emissions
