I would definitely stick with the 7M's harness.

The MKII Supra has a longer engine bay than the Celica's, make sure it'll fit.

so i pulled my exhaust, transmission, drive shafts, engine and when i pulled the engine i left connected to the engine, the giant cable that goes along the firewall and into passenger side and it contained all the wires that the ecu connects into, do i also have to take everything that the other wires from the harness were connected too...?

will my other connecters not going into the ecu but sit beside it, will they fit into the connectors of my 84 supra ?

The rest of the harness will more than likely take some tinkering on your part, as most of those deal with underdash, gauge cluster, and body controls (lights, horn, power distribution). And I'm pretty sure the body plugs aren't the same between the mkIII harness and MkII harness.

Possible 2jz lower block swap in the works if I can't rebuild the 1j. So troublesome.
