It looks like they forgot to plug in that wire to the left of that thingy, and your brake rotors already have excessive rust on them. Both of those could present a safety hazard.
Sorry, I haven't been on to comment. We have been tremendously busy in our household with my daughter just about ready to give birth to our first grandchild. Anyhow, we now have the car totally finished. It is very awesome! The PHEV works great and the totally EV mode is unbelievable! I chose plug in supply because: they were inexpensive, I could get it now, Steve Woodruff of autobeyours.com installs it, and I can upgrade to Lithium in the same box and they are telling me the same inverter. I can't believe all the features that this car has. I spent incredibly less than you can believe having a wreck redone. Talk about the ultimate in recycling. The photos I have previously posted were the very first ones. 12 weeks later and voila! The final product! www.phevprius.blogspot.com
