Aftermarket Tachometer Help
 

91 Miata 1.6 OEM Ignition System
I Got an Aftermarket Tachometer because my stock one gave out, Im Confused as where the Green wire Goes as it's the Signal, its pretty confusing as it goes to the distributor and with my Stock Coil Pack, I Dont know where to Install it, I Dont Use the one Going to the Cluster because it might give me a bad reading as the one on doesn't Work.
Im sure there is someone here that has installed one
