Any Pictures/Drawings Of Underside Of Prius?

Are there any photots or detailed drawings of the underside of the 2005 Prius?

I accidentally drove (slowly) over the end of one of those cement parking space stops, I don't know what they're actually called, I heard some scraping. When I checked, I saw an area that had been scraped, but I don't think it was anything vital, just car frame, (not that I'm happy about it) while I was looking underneath, I saw a short length of tubing or insulated wire(s) right about in the center or right of center under where the front seats are and I was wondering what that is.
The stiffening plate and its bolts were not scraped, just some of the frame under the front passenger area. Should I worry about rust now? Could I spray some primer on the scraped portion to inhibit any rust?

Thanks in advance for your help/suggestions!

Thanks.
The part I scraped is circled in RED, the wires/tubing I have a question about is in Green, the actual wires/tubing is not visible in this picture, but this is the area where it is.

 

So, does anyone know what the wire or tube is that is in the green circled area in my last post is?
It's about 6 to 10 inches (15 to 25 cm) long and seems to come out from one part of the underside and go into another part. I don't know why it's not totally internal to the car. It looks to be 1 or 2 wires in an insulating sheath or tubing.

Thanks again.

 

Thanks Rick and Pete.
