(Question) HEI Internal to external Coil Conversion

[Custom/20]

Hello everybody! I have a question about wiring a external ignition coil. Right now as you can see i currently have a HEI distributor with the normal internal coil and am wanting to switch over to a external Coil so I can use my stock tach that doesn't work with hei. I found this part that allows me to switch to the external Coil but am not sure of what else I would need and how to wire it. I tried looking up a how to but can't really find what I'm looking for. I will link all the parts that I have selected down below.
