Dual Capacitor Wiring

I am just learning how to change capacitors on my AC. I am having trouble with wiring an old capacitor to the new. Its a dual run capacitor with a hard start attached to it. It looks as though the fan capacitor went bad a while back and instead of changing the whole capacitor, they just added a new capacitor for the fan. Does it matter which lead the wires go onto as long as the wires are attached to the correct terminal? I understand I cannot attach the fan wire to the H terminal. But on the fan terminal, does it matter which wire goes to which prong? I dont see a positive or negative or anything like that, and the new capacitors prongs are set up a bit different in the H terminal. Any help would be great.

Welcome to the forum.

As far as I'm aware of they don't use hard start caps on the fan motor..... just the compressor.
These are AC caps and there is no polarity.

Does your fan motor have 2 brown wires that includes 1 with a stripe?

Are you wanting to install a dual capacitor to serve both fan motor and compressor when you now have 2 capacitors doing this job?
