| Harv its different to Bip models that use a 1.6M ECU they only have the one sensor, your SP has two sensors one picks up off the flywheel (RPM sensor P8 only) the other of the cam drive gearing (injection timing on P8 equiped models) and (Engine sensor on the 1.6M equipped models)
As for markings I haven't got my engine here at the moment so can't tell you how mine is marked up. But I doubt if connecting them the wrong way will cause any problems other than the bike isn't going to start. |
