Installing Ext. Timer Switch

Iím unable to understand how to replace the existing ON/OFF switch with a timer switch I just bought from my local HD store.

I have attached 2 pictures, one is from the new timer switch with the suggested wiring connections and that I understand.

The other picture shows what I see when I remove the 2 existing switches which are located in the entrance hall. There are 3 cables coming into the box (each with 2 wires) and the problem I have is that the exterior lights switch I want to replace has 3 black wires connected to it and I donít know which one I need.

Can you explain how I should wire the new timer switch?

Thanks

The two black wires on the one end of the switch are the LINES. There is a place on your timer to put two wires in one screw terminal. The other black wire is the LOAD. You will have to add a short piece of white wire to that three white wire splice and the NEUTRAL on the timer.

So one black goes to LINE and from there another black goes to the second switch. But when the timer is OFF would the power go to the second switch?

Thanks Pete

The two black wires get connected together at the LINE terminal on the timer.
The second switch would always get power.
