Brown wiring for Fan Run Capacitor might just be standard. Am I seeing a Compressor Start Capacitor behind the others? More I look, probably just the reflection of another capacitor. All our stuff is so rusty I can't recognize a shiny surface...
For the OP, the RUN capacitors will generally have metal cases, like Fred shows. START capacitors usually have plastic cases. You'll always have Fan and Compressor RUN and maybe Compressor START.
We have an appliance parts shop right down the street. It has one of those electronic signs that can say anything. Right now: CAPACITOR CITY
The swimming pool supply store nearby also has capacitors. At stunning, triple-retail, prices. If you can wait, Amazon has a lot of capacitors and many are free shipping. FAN RUN is probably 7.5 mfd at 370VAC, and 440VAC works as well.
