Last night as I was driving home, my speedometer needle started going crazy. I was cruising along about 80, and the needle started dropping and raising, bouncing back and forth from about 60 to about 80. Then it got worse, bouncing from 20 to 80. Finally, it quit altogether. I'm now a permanent 10mph as it rests on the peg. I understand that the connection to the speedo is pretty basic, where should I look to be sure it's hooked up? If all is hooked up, how much is a replacement going to run me?
