hi,lpg plumbed in,now the wiring.
I have an unusual old lpg switch,,manual control knob 4 clicks round,4 wires,- + p g (earth, live,live to petrol cut out,live to gas cut out).
All wiring diagrams explain about electronic switches and talk about a pulse live from HT or negitive coil.
my switch isnt like that so am i to assume,that the wiring,(minus fuses at selonoids) is as my below scribble? thanks all

your GREEN bits ... the coil attachment is only used as a sense wire to detect the engine turning , that is so as soon as the engine stops the GAS stops too ..

the + on the switch should a fused / ign switched live ...
