Hey guys,
Im in the process of installing Zeitronix wideband 2010 model and boost sensor on my EVO IX. Wire #8 is different. Its White/blue, not brown. What to do about it?

How to threads show this diagram:

ZT2 Pin # for EVO 9
1 (red) – I tapped this into ECU pin # 47 wire (Battery)

2 (white) – don't use

3 (green) - wired this to ECU pin # 45 wire (tachometer)

4 (orange) – wired this to the Green Boost sensor wire

5 (white / blue) – not used yet, but I will wire the Alarm /
Light later

6 (yellow) – wired this to the Red Boost sensor wire

7 (Black) -- ECU pin # 46 wire (sensor earth)

8 (Sensor Ground) -- ECU pin # 49 wire (power ground)

9 – not used

10 (grey) -- ECU pin # 78 wire (TPS)

11 (brown) – wired this to the Black Boost sensor wire

12 – not used

2010 model of Zeitronix is a little different so there is no #8 brown wire.

This is 2009 and older zeitronix pinout:

What to do? Is there only 4 connections to ECU now instead of 5 before?
Can anyone help?
Thanks

Spoke to Zeitronix today. They said that if Black ZT wire is already connected to ECU black ground then there is no need for another ground. Also it wouldnt hurt to connect Brown ZT wire to black ECU also but not needed. Just a peace of info for anyone instaling current model.
Thanks
