Turning an unneeded outlet into a light switch to power LED lights

I would like to turn an outlet into a light switch to control I light fixture at another outlet in the wall at another location. I already installed the new outlet (that I’d like to have power when I turn on my new light switch) and ran new cable from this location to the socket I’d like to turn into a switch. Hope that doesn’t sound too confusing.

My question has to do with the wiring. I already fished my wiring through the necessary spaces and I just need to know how to connect it all correctly. Would I disconnect the wiring at the outlet and then use that as my power source and wire it in this way I outlined below?

Turn power off at circuit breaker panel first, of course.

Black – hot from power source to light switch
Black – from cable leading to electrical box to light switch.

White – neutral from power source to white cable connecting to electrical box
