i was making a dropshot mod, i already now that i can solder 2 wires to b, and add a button, but i wanted to make it so that it press b, every time i press rt(or lt), i have tried connecting the b wires together and connecting them to a on/off switch(not a light swtch), and having the other wire connected to the middle point on the right side(the point in the middle of the 3 points on the right side of the controller
