Today I received the parts listed above - an electric air solenoid and switch. Now for the theoretical questions:
I'm going to replace all air lines and install these components. Do I run the factory size line (5/16") or a smaller more responsive line size? Do I install the valve near the diff or near the engine? What will activate the diaphragm at the diff in the fastest manner? I know small vac lines offer a faster signal, but the large diaphragm needs a large volume of air to be removed so it will shift. I assume the small ports in the solenoid will be the limiting factor.
