Tach wiring for M20 car

[FileCabinetRacing]

I’m carb swapping an E30 323i and now when I’ve gone to turn it over I am not getting any electronics. I figure I’ve removed and disconnected so many things I’ve hit something critical to the original L-Jet, so I’m just going to do a new harness with just the stuff I need.

I figure the E21 ignition system is pretty similar to the L-jet e30 setup and was wondering if any of you have electrical diagrams or something of how the tach, distributor, and CDI box are inter-connected?

Thanks for any help,
-Charlie
