Honda Repair: Temp gauge/speedometer, vehicle speed sensor, gauge speedometer

Question
I have a manual 1988 honda civic lx, that I love, might I add, but for functionality and safety purposes, I have two concerns. One, when I got the car, the speedometer didn't work. It hasn't to this day, and I can find no loose wires, but maybe I'm just not looking in the right places. Location and type(electronic or mechanical) would be great info.

Second, When I got the car, the thermal gauge worked fine. I had a hose blow at a pressure point and when I cut the hose before the hole and reattached it, I must have knocked something loose, because the temp sensor doesn't register heat at all. Maybe I knocked a wire loose in the process. Again, location of sensor would be wonderful information.

Thank you for your time!
