I am trying to change two ceiling fixings in one room. They are both connected to a dimmer switch(with 2 knobs - 1 for each light). After removing both the fixings and rewiring them to the nex fixings, the lights do not work anymore. The first fixing is wired correctly as it was a simple 1 cable(3 wires) but the 2nd fixing has about 4 cables with numerous wires coming out of it and I do not know how to wire them correctly. Any help would be appreciated. Thankyou.
