Bought 2008 Prius - Overheating (Red Triangle)

I think I found where the leak is while attempting to replace the 3 way valve … still working on that. Fluid everywhere but will finish tomorrow hopefully.

There seems to be moisture on the cabling right in the middle of the photo. Maybe not though, it doesn’t make much sense since most of the fluid / crust I’m seeing is on the opposite (driver) side of the engine bay.

 

Can anyone tell me what is under the Inverter side that would be leaking this much / have crust? That definitely looks like where the leak is just not sure what I’m looking at.

I am not sure if the engine/motor extend to the driver side of the vehicle but if so then the pink crust is on the engine I think.
