I have a 5 speed 2jzge from out of a mk4, harness and ecu.

Along with pedals and drive shaft from another sc

I don't want my sc to be down long. Will the harness from the mk4 plug into the sc300?

1995 supra to my 1993 sc300 auto.

Body Plug connectors between the SC and the MKIV are not the same . So it is not a matter of repinning . You would need the body plugs from the SC300 .
