I have a MakerHawk 1.6" 130x130 LCD module that I am trying to connect to my Mega. The documentation shows the need for an ESP8266 D1 Development Board that I don't have and I don't think need. How do I wire and code it? I have looked at all threads that are similar to my situation, and none have the solution I am looking for.
My usage of the display is just to display text, and sometimes, images. My ports are as follows
VCC // 5V
GND // Ground
CS
RST
A0/DC
SDA
SCK
LED
Please post a link to the actual screen that you bought. e.g. Ebay sale page.
Yes, I could Google. But if we have the genuine link we know exactly what hardware you have got.
Incidentally, I guess that most new Users read a few of the current Forum posts before posting their first messages.
In which case they would see my posts. And they would see the Moderator "stickies" for reading the User Forum Advice.

The display is safe to use with a 5V Mega2560.
Just connect:
VCC // 5V
GND // Ground
CS GPIO
RST GPIO
A0/DC GPIO
SDA 51 MOSI
SCK 52 SCK
LED GPIO
There are several libraries that support this display. They have constructors that require CS, RST, DC, LED arguments. So allocate pins to suit your wiring. And specify these pins in constructor.
Avoid digital #0, 1, 50 but all other pins can be used.
I have a library but it is not public.
ZinggJM has a library
LCDWIKI has a badly_spelled library
...

Thanks!!!!
wait so GPIO is any digital pin. and 51 52 are the ones that have to be in that specific spot?
Yes, 51, 52 are Hardware SPI pins. So you must use those specific pins for SDA, SCK.
I strongly advise you to use a different colour wire for each connection and write down the colour with the pin names. e.g. GREEN SCK, 52 or ORANGE RST, 48
It will help you check your wiring. And if you post a photo, readers can check too.
