Cruise Control diagram on 1991 Ford Explorer

The cruise control doesn't work. It's an automatic transmission with V-6 engine and 4 wd. Is there a detailed diagram somewhere to show the layout? We've checked Chilton's manuals #26688 and 26664 (only ones available) but they don't show what we're looking for. Thanks! Rudy
