I am having difficulty connecting a new timer switch to control 2 external wall lights and would appreciate some advice.

The cabling from the 2 lights is coming in to a single gang switch with L, L1 and L2 terminals.
The cables are connected to this as follows:
2x red wires (labelled as load) connected to L1
1x red wire (labelled as live) connected to L
L2 not connected
3x black cables are all connected together via a separate connector strip

The new timer switch has 'Neutral', 'Live' and 'Live Output' terminals
So it is not immediately obvious what goes where!

Thanks in advance.

Pictures speak more than a thousand words.

(but a guess is the neutral is all the blacks)

Pictures please.

Picture of existing switch wiring attached

It does look like I suspected.

The live (single red) go into the "Live" on the timer
The switch wires (Double red) go into "Live output" on the timer
The blacks (all of them*) go into the timer "Neutral"


* If you don't have room in the timer terminal, you can take another (black) wire from the existing choc bloc and connect just this.
