I have seen DIY writeups on this install but the wiring on the SH 02 sensor is different. I havent attempted to install it in a few months so i forget the details but does anyone have a DIY or any info on the install on an SH ?

 

Why not just weld another bung onto your exhaust? That's what I ended up doing and it seems like the easiest way...

 

That is what I am begining to lean towards. Would prolly be alot simplier in the end.

 

why are you trying to wire it to the SH 02 sensor?

 

No an SH o2 sensor is different than the base. I dont know if its just longer or something but its different and all the writeups Ive seen the wiring is different colors and Im not sure how to hook it up. But like Hawkze said I will prolly end up just getting another o2 bung welded in

 

Yeah just weld another bung....unless you plan on using that whole self-tuning thing that hondata has, there is no reason to do all the work to get it to work the other way.....

If you want to put the wideband in place of the factory narrowband then go to PLX's website, it'll tell you how to wire it.

 

isnt there like two wires you have to wire into the ecu wiring harness? the m300 should have come with the wideband sensor, harness to connect sensor to plx gauge and a narrowband, wideband output, ground and power wire. Just wire the narrow band and ground into the ecu harness and find an ignition power wire to tap into to power the gauge. PLX has a writeup and so does the instruction manual that comes with it. and if you dont know what pins the narrowband and ground go to the prelude FAQ, should be some ecu pinouts in there somewhere.
