i own a 2 litre 16v 406 coupe and i have brought a 2 litre sri turbo to put in to my coupe. The engine runs off its own ecu thats sits in the engine bay. Does anyone know if i have to take the wiring from the sri that sits under the dashboard or can i just join the grey and red plugs that sit next to the battery. is it going 2 be as easy as plug and play?
