The cable between the switch box and the light fixture is called a switch loop. The black wire in the cable going to the switch box is connected to the lamp fixture black wire. This WHITE wire should be re-identified to some color other than white, grey or green at both ends. The black wire from the power supply connects to the WHITE wire of the cable going to the switch box. At the light fixture the white wire from the power supply connects to the white wire on the lamp fixture. The incoming power (from the circuit breaker panel) also goes to the light fixture. The two-conductor cable on the left goes to the light fixture. I can describe it but maybe Ray can post a drawing as well. I would REALLY appreciate any help from the knowledge base.thanks in advance! I'm sure I am am missing a ton of necessary information. The manufacturer's installation instructions are below, but not really helpful: The Blue, Black and White wires coming from the bottom of the photo are from the timer unit. The Black/White wires with the yellow tape on them have not changed/or used, I put those on to avoid confusion.

I also included the wire configuration that I came up with (for better or for worse). The picture below is of the EXISTING switch that I replaced. How do I connect the rest of the wires and do the White/Black wires at the top of the photos do anything? Not a 3-way, single pole I believe, but the existing switch has 3 positions (don't think there is another switch in the house that controls this light). I know the Green is ground and Red is not used. Hi All - I am trying to wire a SunSmart Digital Timer (SKU 15312).
