Well, if I contribute nothing else... I sure am good at starting lively discussions!

Regardless of how I end up finishing this thing off, I'm really enjoying this debate.

PS

The homemade A1 control is working perfectly... Well, except for the false hold condition, but that is nothing to do with the A1 control.

And anyway I like the flashing light....

Basically everythig is working how I want.... I'll sit back now and watch the debate about how things should be wired......

In any event, Thanks for all the discussion!
