1998 aristo speedo not working. Possibly tampered with. Photos attached
 

Hi people. Just looking some advice. As the title says. Speedo doesn't work but cruise control does so figure it is picking up the speed from somewhere. I have attached some pictures of the wiring. Three t
Wires have been joined together. Any advice would be greatly appreciated. Cheers
