Need help with my led strip

I need help with these led strip, they wont turn on i have tried different connection and nothing. These are some crappy led strip i don’t know if where i hooked them up on the esp8266 board or might be the settings I’m at a lost.
I harvest the stock connector from the original wifi box and solder the wire to the esp8266
The plug colors are odd they are as followed
Black wire-12v
Red wire -G
Green wire-R
Blue wired -B

Those will be analog strips, you’ll need to add external MOSFETs to drive them.

Do you which MOSFET i need to get?

Check out some examples in the Knowledge base.

Scroll down to the 2nd image.
You’ll need one MOSFET per colour channel (3 for RGB).

Thank you,
Last question which pins would i solder on for red,green,blue?

When you chose your LED type in Config->LED Preferences->LED Outputs, you pick PWM RGB.
You’ll get 3 different GPIO pins to pick, one for R, G, and B. Those are the pins you connect to the respective MOSFETs for your R,G,B strip drivers.
