I got tired of having a blank dash bezel in all my past barracudas that I had. So, when I purchased my notch, I also bought a tach from the seller. He said it was correct for 1968 but I am not sure. It was hooked up in the dash with what looks like a lamp cord. The cord was ran to the motor and nothing was wired from there. Can someone let me know how to hook this up and what to use for wire? I figure the lamp cord probably isn't a good idea. Does the short copper plated stud go to the coil(-) side? Where does the wire from the silver stud go to. I attached some photos. Any help would be much appreciated ....thanks
