My Lenovo 65W Usb C charger died, male end that plugs in went bad. Cut off the end of another usb C cable. Thing is, the Lenovo charger wires have the thick foil, a red wire and a blue wire.

The usb c male end that I'm trying to attach has black red white and green. Sadly I don't have access to a multimeter right now so I have no way to figure it out through that method. Looking for some help.

Are you sure it's the charger that went bad and not the port on the laptop? I have seen quite a few USB C ports fail but very few chargers.
The male end of the cable went bad. I can charge my laptop with my nintendo switch charger it just charges slow and the cord is short. I had s spare usb C cable I figure I'd be able to splice to the end of the Lenovo cable to fix the issue and give it extra length.

You need to go buy a cheap multimeter. They can be had for not much over $10 (just one step up from junk but good enough for what you need). Make sure to compare the voltages to the nintendo charger before you plug it in.
