Tinkering:
I downloaded fritz and drew up a diagram. Might be missing a diode protecting power to ground on the device and resistor on trigger to gate. Below should be an imgur link. The power for the nodemcu (esp-12e) will come from a usb to the car battery. For mosfet Ill either use a TIP120 or IRLZ44N . A link to the device Im using is below and I want to leave a 100ma capacity for adding a smaller device of similar power configuration.
Sorry, but you will be better off drawing your circuit by hand and posting a picture of it.
Fritzy images are pretty hopeless as they don't reperesent the components properly, or labels for component leads/pins.
Please read the first post in any forum entitled how to use this forum.

It will show you how to post images.
