That was me. Long weekend silver zx do gunna retime my engine and pull the alternattor off aswell (now running same as you) to figure it out as ive got a huge tacho stuck to my dash doing nothing. Annnnnd no it isnt possible to run an aftermarket tacho off the standard wires. The whole reason it works off the w terminal is it picks up unregulated voltage and signal and works from the pulses or something I rather forget but it needs that kind of pickup not a regulated signal such as the standard sensor
