How do I connect this module?

I was given a similar module a while back because nobody could figure it out. The wire colors do not match any reasonable scheme. So you need to open the case and do a bit of tracing.One lead should be the common, which is simple to find since that connects to many parts including the filter capacitor negative, one lead connects only to the output control triac, one lead connects to a small capacitor, and the power hot lead connects to a resistor and the other power terminal on the triac. On my module only the yellow touch lead was correct.
