Wiring wideband O2 controller in a 92 si hatch
Just a few quick questions regarding installing a Wideband O2 sensor and controller.
1. Can I use the stock O2 heater element wire to power my controller? If so what is the color and location of that wire on the harness of my 92 si hatch?
2. What is the color and location of the stock O2 sensor signal wire?
Any help would be greatly appreciated, my stock o2 sensor went **** up during a dyno session over the weekend and I don't wanna drop the dime on a replacement so I just pulled my techedge WBo2 from my Datsun 510. I really just wanna get my part throttle fuel economy back and get the stupid CEL to go dark again.

Just so I understand correctly... you are replacing your stock narrowband with a wideband?
I can't remember, does the techedge have a narrowband output that you can feed into the ECU? I guess it must or you wouldn't be doing this! LoL.
Anyways,
1. I'm not sure if you can or not. I don't see why you couldn't though. I powered my wideband from a different source at the ECU. But I kept my stock O2 sensor in there so my wiring will be different than yours, obviously.
2. It's the green wire.
What ECU and EMS are you running?

You can if you have a wideband controller with a narrowband output. (which most of them have)
Lot's of people do it this way.

Yeah, my techedge has a narrowband output which I will be feeding to my hondata s200 equiped ecu until I get a chance to get it back over to DynoSpot Racing in San Jose where I hear they can modify the ecu to accept the 5v linear wideband output and remap the fuel curves. I'll probably just run on the narrowband output for a few month till I get the fund together to buy bigger injectors, adjustable FPR, and a GSR fuel pump. I mean I'd rather not have to pay for two seperate dyno tune sessions if I can get it all done in 1 session.
