How to control Sanwo Relay TK73-1624 module with JQC-3FF 5VDC-1zs(551) relay?

Question

Arduino

Good afternoon, please help me figure out how to start working with a relay module from China . I have such a thing and arduino
mega (china) in addition . it is controlled by supplying + from the arduino 5v port to COM + and opening the arduino pins with the input_pullup function, I connected 16 module contacts to arduino mega contacts from 1 to 16 , as a result, the board in such a connection does not even allow itself to be flashed, what am I doing wrong? how to properly manage such a module?

You can’t see all the signatures on the module in the photo, but the essence is as follows.
1) The module needs power (not just "plus"). It is better for this bunch of relays to take it not from Arduino, but from a separate source. Connect the earth.
2) The "input_pullup" function does not exist. There is a pin mode "input_pullup" set by the pinMode() function. The state of the pin is changed by the digitalWrite() function
3) The relay is turned on by applying either a high or low level to the corresponding pin. What - you need to find out. (Modules are both such and such and switchable)
4) Regarding "not being flashed". At the training stage, simply do not use pins 0 and 1 on arduins for your needs. Until you figure out what they are responsible for.
