I just received my replacement HV battery... the donor vehicle was a 2016 Prius C. It basically came "plug and play" with the fan and everything. Do I need to swap out the battery's "ecu" or anything? It's going into a 2013 model. Thanks!!
I believe references to ECU swap you may have found were because most replacement packs are delivered without any ECU at all. I don't know if your car is going to care about a new ECU showing up in place of the old one. If it were me I'd put in the complete new pack. Best of luck!
