I have and existing 3 way switch on the wall that controls the upstairs light, lounge light and a porch light. There are two twin and earth cables and a single that enter the switch. The first one - Red too 1 WAY - Black too 2 Way (at top right). The second one - Red too Common (bottom right) - black too 1 Way (top left). Single cable connects too 1 Way (bottom right).

2 Way 1 Way Common 2 way 1 Way

Common 2 Way 1 Way common

I have put a new light on an existing wall. I want too get rid of the porch light and put the new light onto this switch so it will eventually switch upstairs light, new light (2 wall lights), lounge light.

Would appriciate any help on where new connections go. or any sugesstions. cheers.
