I am trying to get my water temp gauge working of my 64 fleetside so I can get rid of the ugly aftermarket one. My father in law beat this truck to **** and let rinky-dink mechanics jury-rig any thing so he could get to work...The green wite coming off of the instrument cluster harness isn't connected to anything. Where or what is this supposed to be connected to it. there are many more also the thrift heater switch has one of its wires cut. I have included pics below. Any help would be great!
