Corsa Dual Fuel, fitted from new, All I can tell you about the system is that there is a aluminium cylinder with a wiring connection about the size of a fuel filter ....which says "NECAM" on it.... which is fitted inline in the fuel line, at the bulk head in the engine compartment, about 8 inches away from the "common rail" pipe (a welded piece of sealed stainless steel pipe which feeds each injector site).
The switch for LPG is on the centre console infront of the gearstick.
I've been a bit of an idiot, I had to remove centre console and the wires on the switch and can't remember which order they came off.
nearest the gear stick is the LPG position and the Petrol postion is nearest the engine side.
There are 2 positions for the switch LPG/Petrol
there are 3 wires grey/Black, Red/Black, Red,Yellow
3 contacts, one nearest gearstick, one nearest engine, and one in the middle
I believe the grey is the nearest gearstick (the LPG one)
I believe red/black is the middle & Red/Yellow is engine side
Can anyone confirm please?
Thanks
