The V8 Owners Forum -

just got myself a couple off ebay

these are the dual timing ones for petrol and lpg

i dont use lpg so is it possible to wire it in and use it anyway???

i got the instructions with it but its all mostly about wiring for lpg

could i wrap up and secure the lpg loom from it and use the black and red wires alone for the loom to the dizzy

i dont fancy ringing rpi as i didnt buy them from them

nope dont worry ive since found out there single timing so im all set

Just in case you still care , you can still use it with petrol alone, but your the position of the dizzy will always be about 10 dgs advanced to what you normally run.
Just blank off the blue wire asw that's triggered by the LPG solenoid.
Either that or connect the blue wire to the +12V on the coil and you're dizzy will always be in the correct position.
