i want to wire up a light that comes on with the ignition and goes of with engine
running on a ZR160 2002
i have tried an ignition live to one side of the bulb and connecting the other side to the wire from the alternator to charge warning light bulb this does not work as the wire does not go to earth when ignition is on

was thinking of oil pressure switch with but believes this goes through engine ecu
