Tach wiring
Hey all, can anyone give me a simple version of the wiring on the back of my '74 1.8L tach? I have perfect ground, good bulbs. I checked continuity, fuses, relays, but referring to my wiring diagram which i am confused about, added to the fact that I'm a contractor, leads me to believe that I need advise. My tach is functioning, I had it tested, so which wire goes where? Thanks for any help!

Looking at the BACK of the tach, far right terminal is ground, center terminal is the signal coming from the engine and far left is +12V power when key is on. Hope this helps .. Bob
