So I have rebuilt the Sisley, engine now in, I have worked out the immobiliser wiring just need assistance on the ecu engine wiring. Do I just plug into main fuse box and connect the ignition to live? Any advice greatly appreciated!!!

should be pretty easy, i put a p75 (1.2 8v mpi) in a carb'd car. I basically left the cars wiring alone, used the fuel cut off switch wire as the switched live for the engine harness. I think the only other bit of wiring it needed was the fuel pump - i mounted an inline pump where the coil pack normally sits. To get it running i just earthed it to the body - never did finish that part properly but plan was to fit an inertia switch somewhere inside, cinq or sei one probably fit nice up behind the dash and run the earth through that to the body so if you crash the fuel will stop pumping.

I did strip down my engine harness and remove unnecessary wires but you needn't go that far.

oh, a thing to consider is fuel lines... they will be old and they won't be specc'd for injection pressures.. its pretty easy to just run new lines all the way back.. I used nylon hardline under the car and new rubber in the bay.

Thanks, I have put a pump in the tank wit an inline pressure regulator. I have an issue with the fuel line connector on the fuel rail, once that is on I should be in a position to try and start it
