I recently replaced the cylinder head on my 2002. Trouble shooting after getting in running revealed I need to replace the EGR valve. That proved to be something of a challenge (as was all the other work). Not the the cruise control light comes on, but it won't engage. What's wrong?

 

Recheck the vacuum lines at the back of the engine. The vacuum line to the speed control servo runs by the egr valve and may have become dislodged.

 

Is there a diagram somewhere of where all the hoses go? I know I got the lines from the block mounted EGR valve to the round black plastic unit behind the throttle body right, but not sure of any of the rest of them. There is a hose that connects to a fitting on top of the throttle body. I connected it to a junction fitting that is yellowish in color, but not sure that is the correct way.
