Since I do not have to worrie about emission control, do I NEED an Air diverter valve?

In my orignal post, question #1, for the N/S switch, rfmaster said to leave it open. Can you elaborate? open=not hooked up at all?

If I go with a stock harness, $ is always an issue, for the wires I dont use do I just cut them off?

I do have headers on my blazer. So I will need a 3 or 4 wire o2 sensor. I will also need to weld a bung into the header. I have read keep it within 12" of the head...is this correct?

Can you please explain how to"wire a simple relay controlled circuit to turn heater when ignition is on"?
I am no electrican but did google relay info and have a very basic understanding. Please correct me if I am wrong, but there are always open or always colsed relays....and a relay is just a switch operated by a current?? correct?
