The seals are all stock Toyota.
I don't know what will be left of the harness, but you're more than welcome to it.
The motor is already out of the car, but I still need to remove the harness and whatnot. Should be done in a week or two.
The gen3 motor only came in jdm cars and started in 93. The only reason to go with the gen3 wiring harness would be to remove the AFM.
