The plumbing varies, but the result is the same. On my '95 there is a short hose from the intake manifold to the AFC and another short hose from the turbo output to the waste gate. That's the same setup as BSMcCauley describes. The seperate setup like ours may be less affected by a waste gate leak than the type with the T. Regardless there has to be enough boost to move the AFC foot throttle stop in order to have more fuel to create more boost to move the AFC foot more and so forth. If the diaphragm in the AFC is bad or something like that the whole process doesn't work.
