Theres no "probably" about it ..!

Almost ALL the wiring is unique to ST170 (It's Yank) You would need 14K733 (Engine base wiring) including the hard-wired Bay fuseboard, 12A690 (Engine) and 9H589 (Injectors) Engine wiring, 12A522 from ECU to Engine/Fuseboard and Fuel Pump, plus there is a Pump pressure/volume control unit near the back, pump assy, plus box/remote .. AND you have to use the right stuff as a donor car could be (+) or (-) ESC(IVD) (Stability System)

Hope that makes your mind up for you ; )
