Fuel Injectors harness

Hi, I am in the process of buying a '92 Celica All-Trac and need the four fuel injector conections with the harness. I was told the fuel injectors from a MKIV Twin Turbo fit the 3S-GTE fuel rail, so the harnesses should be the same.?? If this is right I would like to know where I can find the harness. Thanks

RC engineering has them brand new.
