There switch which turns the lpg solenoid and tank solenoid on has a few wires going to it... 12 V + Ground Solenoid Neg Coil. The first three are easy, const power, earth, and power out to the solenoid to open it up and let the gas flow. Problem i have is i dont know where to find a 'neg coil' source. The coil pack on a vl isnt like an old carby style coil with a big + and - terminal, so where else would i find a negative coil line source? ta

get a workshop manual, find which wire on the coil is the negative one and tap into it the basic design is the same as older style coils its just been made more compact

There is a test wire hanging just behind the altinator, brown with a red stripe! If you cant see it strip the loom back a bit and tap into it!

you're a gun JET-6 GUY! i didnt want to strip and tap wires because its messy :P i have a factory vl turbo workshop manual, unfortunately my car is non turbo, and.. have you ever tried to read the wiring diagram in the back of it!!! my god Some original photos have not been recovered yet.

Yep i read them everyday, easy once you know whats what!!
