Tach not working
I not so recently bought a 83 rx7 that runs well, only problem is my tach just doesn't work I know it probably has something to do with the msd 6a ignition system that came with but I'm lost even after doing some digging so please any help would be appreciated please and thank you

The tach gets it's signal from the coil. How is yours wired up?
