What's the best way to go about wiring on a BNR32 with COP ignition? Do I have to tap into the coil power wires for a signal or can it be done from the ECU? There are 4 wires:

Red = Power
Black = Ground
White = Illumination
Green = Trigger

There's also a brown calibration loop wire, which I know needs to be snipped open as this is a 6 cylinder engine. I snapped some pics of my tach and a rough schematic.

This is my first time installing an aftermarket tach, anything else I should know before I get started? Thanks guys.

for the signal wire take it right off the trigger side of the ignitor.
