RE: (ET) Controller Needed?

["Elie, Larry \(L.D.\)" <lelie ford com>]

Perry, that's basically what relays & contactors are; high-current remote 
switches.  Switches that can 
handle 100 amps are big, so we remotely switch them as relays.  A low 
current switch near the dash turns 
on a big one, at the right time, in the right sequence, elsewhere.  The ET 
is really all switches.  Unless 
you get a new controller, and then you have another story.

I am not an electrical engineer, so please be kind if this is a stupid
question.

Why is a controller needed at all?  Can't on just hook up switches and such
to:
Turn to Drive power on.
Set reverse.
Throttle.
Etc.? 

Has this been tried by anyone?

(I have an Alltrax controller, so I was just curious...)
