Celica Forums News Portal r/Celica Need Help Buying '01 GT-S Wiring Harness [r/Celica]

I am working on a MT 2001 GT to GT-S conversion, already completed the engine/trans swap as well as part of the Monkeywrench racing conversion kit.

I can't seem to find any new parts,and the wording on many eBay ads has me confused or seems only partial. Can someone help assist me in exactly what all I need for the ENTIRE/COMPLETE electrical wiring system minus ECU?

Does not have e to be eBay, but looking to order these parts as soon as possible, $300+ budget. Thanks!
