Nope, you'll have to get an ECU, along with a bunch of other things (and relocate a few things too)

WRONG!!!!!!

its obviously a rhd harness, so theres a few useless extra plugs on it like the crank angle sensor and what not, its all already on the usdm body harness so stick with it, i gutted my rhd harness and eliminated all the emission plugs, crank angel sensor, checked for heat damage and re loomed it,

BTW if your harness is s4 it might not come with a injector resistor pack, so youll have to swap to high impedance injectors, if its s5 i wont know much on that because i have s4 t2 :-/

helped as much as i can

No wiper wires in the JDM EM harness like the ARE in the USA version.

Common and GOOD sense dictate using your Non Turbo harness on the Turbo engine. Small/minor modicications to be made to the non turbo harness.

Read the pinouts for the Turbo and Non Turbo ECU plugs in the FSM's FUEL Chapter. Sub section called something like CONTROL UNIT or such.

Or buy a series five Turbo EM harness.

86-87's used the injector resistor near the right side shock tower. Early 88's used it too. After that, was a switch to high impedance injectors and no resistor.
