Thanks for the info. The way I spliced it in is unlikely to do any damage. I.E. not actually cutting the wire and instead using on of those connecters that literally taps into it. Thus far I have no had CEL likght come on however ive only driven it about a mile since installation.
I will remove it from that sensor and tap it into the rear one and see what kind of results i get.
With a gauge that has its own wideband sensor where in the exhaust is it mounted? Mine is currently stock back to the cat so there is no place to weld a bung on to mount a sensor.
Thanks for all the help.
