If you choose to keep the 07 dic in addition to the four wheel sensors you will need a 07 keyless entry reciever as well.
This part changed in 07 because it has to be capable to receieve signals from the pressure sensors, The connectors are different just enough that they wont plug in so you will have to splice a connector or make an adapter harness and make a slight wiring modification so the keyless entry reciever has a direct link to the serial bus of the car.
The keyless entry reciever sends the tire pressure data over the serial bus where the dic picks it up and displays it.
The keyless entry reciever will have to me reprogramed for your new remotes, as well as learning the tire sensors.
