280zx tach not working with MSD6 box

My questions is specific to a non-digital dash 280zx (1981 model). Has anyone installed a MSD box and got their stock tach to work without the need to install the tach convertor? . Car is starting and running fine, just can't figure out why the tach is not getting a correct signal. Tach is not registering a signal at all. If a tach convertor is needed in this application, can someone recommend a specific part number/model? I've seen several discussions on MSD with older Z models but not for 280zx applications.

Got tach working by installing a converter box (MSD Part 8920).
