Alright Guys, I've got a Nova Gsi with a 2ltr turbo engine in it. It's got a digi-dash from a astra gte and the rev counter doesn't work. The problem appears to be with the wiring. Does anyone know if i can connect the green wire in the back of the dash to the black and red wire on the coil, even though this appears to go to the ECU? Any help would be appreciated.
The engine is from the early Calibra turbo (Red top).
