Tach/RPM Wire Tap?
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 doesnt 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?

violet/black or green
The easiest place to pick it up is on pin 1 of connector T6c in the passenger footwell. T6c is a green connector. You can see it here, behind the gray connector which has the MAP signal used by the TDS-1:

The vehicle speed sensor is in the same green connector, pin 3, white/blue.
Bonus info:
Throttle position sensor is a gray wire going to the ECU.

The boost will not read properly, but you'll at least see a boost curve.
