The early models had a vacuum hose only.
Late models have both.
egr wire connection
You can purchase a "pig-tail" from the dealer and splice it in.
The egr is located on the front cylinder head where the belts are located, it has a five wire connector an a tube that goes to the intake pleneum. Early 2004 egr's were vacuum and later ones were all electric.
The EGR on a 2007 is not vacuum controlled.
The EGR (Exhaust Gas Recirculation) valve opens when vacuum is applied. The EGR vacuum solenoid opens and closes the vacuum supply to the EGR valve when it is commanded to do so by the ECM (Engine Control Module).
EGR stands for Exhaust Gas Recirculation. The purpose of the EGR system is to lower the amount of oxides of nitrogen the engine produces. The parts of the system are the vacuum actuated EGR control valve, the vacuum switching valve, and the EGR vacuum modulator assembly.
If it has vacuum lines attached to it, it is probably a thermoswitch that controls the vacuum to the egr valve. If it has an electrical connection it is probably a engine coolant temp sensor.
There won't be any vacuum to the egr while idling. Engine must be warmed up and under acceleration or cruising before vacuum opens egr valve.

Both
If it is an electronic EGR valve it is on the top of the engine on the rear left or drivers side it has three solenoids and a wire harness at the top IF YOU HAVE THE V6 (3.3) ENGINE IT DOES NOT HAVE AN EGR VALVE. IF YOU HAVE THE 2.2 4 CYL YOU HAVE A VACUUM TYPE EGR LOCATED ON THE END OF THE HEAD ABOVE THE TRANS.
* Remove the air intake duct from the throttle body and air filter housing * Detach the vacuum line from the EGR valve.Disconnect the EGR pipe nut * Remove the EGR valve mounting fasteners * Remove the EGR valve and gasket from the manifold.Discard the gasket * With a wire wheel buff the exhaust deposits from the EGR valve mounting surface on the manifold
