Hey guys,

I am trying to install a zeitronix wideband O2. I am trying to wire up the Zt-2 module which calls for hooking up one wire to the tach signal, one to switched +12V, one as a simulated narrowband O2.

Where can I find these wires? According to the documentation I have, the tach signal is a white wire coming into C230 plug. Where is this C230, I have the under-the-instrument panel off (looking in the passenger compartment right inside the firewall pass-through), but I can't find it. Pictures would be great, but I understand it may be tough to pull off. There are tons of white wires. I need an easy place to tie into.

Also, my documentation says that any pink wire ("as a general rule")is a switched +12V source. Is this true? I have a DMM, but this would be easier as I am having trouble doing the contorsionist act while having a flash light in my mouth and moving wires out of the way (in the 100+ Deg Texas heat! YIKES).

Where do I plug in the simulated narrowband wire? I am completely lost here. Do I just tap into one of the wires coming out of the removed O2 sensor?

One last question, I have an extra item I can monitor but it must be 0-5V analog signal. Any ideas what I should log (I am thinking TPS)? I am going to use datamaster at the same time for tuning.

Thanks in advance for the help. The more desciptive the better!

Here is what the install says:

PIN # WIRE COLOR FUNCTION
1 RED Switched power (ex. ignition)
2 WHITE Wideband Analog Output
3 GREEN RPM Input. 0-12V square wave, tach signal or primary (low voltage) side of ignition coil.
4 ORANGE Boost Sensor Input
5 Empty Not used
6 YELLOW Zeitronix Boost Sensor +5V Power. Connect ONLY to Zeitronix Boost Sensor.
7 BLACK Power Ground
8 BROWN Sensor Ground (EMS ground reference)
9 PURPLE Simulated Narrowband O2 Output (for your stock ECU)
10 GREY Throttle Position Sensor
11 BROWN Sensor Ground (Boost Sensor ground reference)
12 BLUE User Input 0-5V

 

Bump! Dang the new threads start up fast....

 

TTT for you as well as a question. Can you run these WB02's in place of the factory ones?

 

No. But, on a 94-95 you could run one in place of the one rear o2 sensor. Prefered placement would be before the cats.

 

Thanks! I know I have seen a kit out there that has a dual WB02 setup that can be used in place of the factory sensors because it dumbs the signal down to 0-1v for the ecm. I just cannot remeber who made it.

Yep, you can't run it in place of the fronts but the back O2 sensor isn't really used (I think it is for checking the functionality of the cat). I am getting a new bung welded when I get my new exhaust.

Any info on the install? Guys?
