You have to call around your local auto places, you should be able to buy aftermarket pressure switches locally.
Yep, the knock control is N/O. It has a very low psi setting because you don't need it to work under vacuum conditions or no boost.
Pc is a waste of time and in my opinion Toyota stuffed up on this one. Just earth it out and forget about it. The last think you want is fuel cut under boost anyway...
Pe is good to have as it gives you more fuel when under boost. I think its about 5 or 10% more when its above around 2 psi. Earthing it out means it is also going to run richer instead of just under boost.
