I've been reading about the 1jz gte swap but couldn't find answer. Car is 97 sc300 with auto. I want to swap 1jz into but how does the harness work. Straight plug and play like obd1 or is there wiring needed.

2) if i use the 5 speed that comes with soarar 1jz do i use half sc300 and front half 1jz drive shaft or just 1jz drive shaft.

I'm planning on doing the swap my self but just worried about the ecu since its obd 2. Car is USDM.

Thanks in advance and sorry i tried searching but i failed
