there are no neutrals in switches,all connections are live,the dimmers will have c and 1 2 on each dimmer,how to work out what wires go where,is very simple,but you must be very careful,take one pair of wiers and touch them together,if a light comes on,then you put these two in one dimmer,and put the other pair in the other dimmer,it does not matter abpout colours ,just be careful work on live lights
