sorry i am not entirely sure what they are called, on my playmatic pinball there are some pins in the bottom board on wires, next to them is a row of holes which look like the electrical plugs, do these pins have to go into them holes ? if not what are they for ?
there is also a row in the backbox and some wires lying in the bottom with pins on them, do they go in there as well ?
sorry but its my first em pinball so just learning
