Problem wiring new timer switch, please help
I tried, I am confused and so I am reaching out to you guys who know what your doing, as I obviously don't in this situation.
Near my front door there is a standard light switch which has 2 wires going to it. This light switch controls three lights outside, all go on and off at the same time (the porch light and the two on the side of the garage) when you operate it. There are two wires going in to the switch, both appear black with no white stripe, etc. but the box has lots of paint and on the wires, etc. Inside the box are what appear to be a ton of unshielded copper ground wires bundled together that terminate in a pack. The other two light switches have 3 wires going to them and those are three way switches as I have other areas near my staircase that i can operate and those lights (inside lights and such) which switch.
The switch I bought at Home Depot was this GE Sunsmart digital timer
3-Way Sunsmart In-Wall Digital Timer-15312 at The Home Depot
Here is a link to the wiring guide
There are BLACK, WHITE, BLUE, GREEN and RED wires. The box says for 3-way or single light operation, but I just don't see how I can make this work.
In the picture below the switch on the left with the two wires in it, is the switch that I want to replace with this GE timer. I have a nice digital multimeter which I can use to check continuity and voltage. I know that I checked and obviously one of the wires going to that switch on the left (the top wire) is 120V so that is LOAD I assume? and the one on the bottom is LINE? What do I do? Do I need a different timer? Can I make this work? Thanks!!
Here is the link to my wiring so far ,the switch is on the left that i want to remove.
