Celica Forums News Portal r/Celica Stock stereo harness [r/Celica]

I recently bought an oem stereo for my 2001 Celica GT to replace the aftermarket one that was installed by a previous owner, but the current harness doesn’t fit the oem stereo. Does anyone know where I could buy the cables required to connect the oem stereo? I’ve looked online and the closest I could find was the entire wiring setup for the whole dashboard, but I’m just looking for the stereo harness. Any help is appreciated.
