I went and removed the Petrol/LPG change over switch and didnt really pay any attention to where the 5 wires went to the switch.
So if anyone has a 3 way change over switch that has 5 separate wires going to it (not a single plug), could you please go have a look and see what wire goes where?
i have a Red, Green, Yellow, Brown and White wire.

The labels on the back of the switch are as follows:
+12v, Sender, Petrol, LPG and GND - all going from top to bottom (LPG middle Petrol on the 3 way switch face),

I have no experience with LPG at all,
but
GND should be easy enough to work, (Ign off and no resistance to Negative)
12 v also should be easy enough ign on 12 volts.
The switch takes power from the 12v to the petrol control module or the LPG module, It might be possible to locate either of these and work out which wire is which.
The last wire, a sender, could be either the wire from the lpg tank or the petrol tank.
(not sure how the sender wire would link in to the switching between LPG and Petrol. You may be able to work it out with a multimeter, if it is Petrol or LPG.)
Out of interest what is the three way switch ( LPG middle and petrol) whats the middle position do?

Figured it out yesterday.

The middle of the switch is all fuels off.
Handy if you want to crank an engine without starting it.
