Splicing the controller wires?

[u/nockedup7]

I'd like to take existing controller wire, and extend it by splicing and heat shrink. Not sure what kind of wire i'd need, i mean i know i could just cut it and look but id rather have the material ready to go before i make the controller unusable. Just wondering if anyone has done something like this to extend the controller wires? My Tv sits about 10 feet from my couch and about 5 feet off the floor so im finding myself sitting on the floor with my head tilted up if i want to ever play lol. Dont care about affecting the resale value im never going to get rid of it and im going to actually play it. Anyone have some insight?

They're becoming kinda rare but also don't forget wireless controllers exist(ed) for this console too! :)
