Using a wideband o2 sensor in place of the oem narrowband

Post by sirdelsol »

wondering if anyone can help me here, looking to use my wideband sensor instead of the stock narrowband as an upgrade but I'm failing on trying to figure out the wiring, what i want to do is splice the pigtail from a dead oem narrowband onto the wideband so that i can have it feeding data to the ecu as well as my Innovate LM2 so that its a simple plug and play application, im running a hondata s300 p28 for my auto-manual converted OBD1 b16a, I've seen some places say that you can go straight into the ecu plug but im not looking to do that id rather keep the wiring to a minimum where possible so im really just looking for some wiring diagrams or advice if anyone has done this before?
Thanks

I'm not sure what you want to do that is simpler than using one of the ECU inputs.

well i was hoping to splice a plug onto the wideband sensor so i can just plug it straight into the oem engine harness, not seen it done before from the forum scouting I've done so far

That is not possible as you need the controller to be able to power and read the wideband signal.
