Hello everyone!
So I bought myself a Mayflash F300 and just started modding it with Sanwa parts. And then (idiot as I am) when pulling out the button wires, I managed to break 1 wire at the end near the button. So now my X button doesn’t work and I think I need to replace the whole wire set (for buttons △ , 
, O and X). Can someone help me? I need to find this set of wires, but I don’t know where. I’ve tried on ebay and aliexpress with no luck. I’ve also asked the Mayflash support, but they don’t seem to understand my problem (are they that bad in English?).
You can see this set of wires on the picture below, on the bottom you can also see the broken green wire.
Thanks and have a nice day!
Looks like you broke the tab to the microswitch.
You basically just need to buy this and replace:
Depending on the damage to the quick-disconnect, you may need to replace that part too, but just cut the green wire, and re-crimp/re-solder another quick-disconnect onto it and you’re done.
Hey. No, the button is fine + I have spares. The quick-disconnect is damaged, I didn’t realize I can replace it with a new one 
Another problem occured though, I pulled the green wire with the damaged quick-disconnect out of the “white box with wires”. Will it be ok if I just put it back in or do I need to do something else? (I promise I’m done 4ever with the pulling)
