Does anyone know what the proper wiring is for this combo? I have tried everything it seems and cannot get it to work. I have even tried another factory tach in case mine was bad...? Thanks in advance...

The tach in your car is a current triggered unit, which is installed in series to your original coil. You need an MSD 8920 Tach Adapter for your tach to function. You can get the manual from the MSD site at:
