This post is very old...just wondering if this still works? It says to tap the b1s2 heater signal to the b2s2 heater signal - what does that mean? Do I cut both and splice them together? Or do I find the O2 sim and cut the wire going form the signals to the board? So confused by this pic compared to when I look at my engine. Can you please help me? If you have pics of what needs to be done where that would be even better Thanks!

Bringing this thread back to life! Does anyone have an image of what wires you cut/tape exactly? Is it the wiring near where you connect the sensor? (I have code P0141 S1B2) I have a new o2 sensor on the way but I need to do this mod to pass inspection by the end of this month.

Thanks
