from what ive heard, the vn/p tacho pickup is a brown wire in your engine bay, passenger side off memory... dont have any idea about the VT sorry, hope that helps
jolly_97 is right. It's the brown wire coming from the DFI module (under the coil pack) in the engine bay.
It does end up in the instrument cluster, even if you don't have a tacho as I fitted the VS tacho and fuel/temp gauges to my VP lvl1 dash cluster and the tacho works a treat.
Brown wire.
