Evening guru's

I'm onto the final stage of installing SVI LPG into my VYII 3.8
All I need to know now is..... Which wire is the RPM sender?

The LPG computer requires engine RPM to work.
Is there one on the coilpack or do I tap into the PCM?

Cheers in advance

Brown wire from the DFI module, certainly on the earlier models there is a connector in the engine bay loom for hooking up a tacho.
