[s-cars] Tach/RPM Wire Tap?

[Cody Payne]

Anyone know what colored wire the tachometer wire is coming out of the
ECU wiring harness? In the link below I can tell it is Pin #40 but that
doesn't help me much..as far as I can tell?

Hooking up my Wideband A/F meter (Zeitronix)

However on the 200TQ 20V diagram is says #6 which is yellow/black?

Thanks
