need help with techedge install

[stevel]

Hey all,

I've got the hondata stage 4, the Tech Edge Wideband Unit (Vers 1.0), and an NTK L1H1 sensor. I have a question about how to hook it up. Can the version 1.0 hook up to the O2 sensor signal that goes to the ECU? I'm not sure. This is how I imagined it would hook up:

Take out the front 02 sensor, install the NTK L1H1. Hook the 7pin plug up to the TE box, then send the 2wire plug back to the factory O2 sensor plug with the 1k ohm resistor. Does the speaker wire looking stuff go to the O2 sensor signal and ground?

But the box needs power too, correct?

It seems like the 1.0 box doesn't allow it to be hooked up to the ECU thru the O2 sensor. This image below is the 1.0 box. I did a search and understood how people hooked it up but no one mentioned ver 1.0 or 1.5. It seems like I'm short a connection with the 1.0 box. TIA

The speaker wire is the power connection. The output comes out the DB-9 connector (pin 7).

Check out the manual on the Techedge Site. (http://www.techedge.com.au/vehicle/wbo2/ozdiy-um.pdf)

thanks for the link. I've been on the site a few times and never saw that. I got it figured out now.
