Custom making 360 stick help!

I’m building my own arcade stick since my TE still hasn’t shown up yet and it seemed like a fun thing to do.

I bought a wired 360 controller and scrapped the rubber coating off the connectors. Problem is that no matter how much I scrape I can’t get all the rubber coating off so the the solder isn’t binding very well.

I’ve tried flux and that helps but still not all that great.

Does anyone sale any pre wired boards or is this the ounly route to take?

Gamingwow (Nareg) sell pre-wired pcbs with Quick disconnects.
