The emulator is not connected to an EGR, it is an EGR emulator so the wiring from the engine harness plugs into the emulator and the emulator pretends to be an EGR. This keeps the ECU happy. The actual on-engine EGR is no longer connected to any wiring harness in any way. In case the actual EGR is still open or leaking exhaust gas into the inlet manifold, you fit the blanking plates. This stops any unintentional exhaust gas recirculation into the inlet. You can buy the Tafmet on it's own and make up or buy different blanking plates from somewhere else. Check out the Tafmet website.
The CFCA engine was fitted in T5 and T6 before is was replaced with a Euro 6 biturbo. I asked Tafmet if this works on a T6 and they said it does as it's the same engine and ECU. I can confirm it works fine on my 2016 T6 180 CFCA.
