Are you serious? That was just a step over just twisting the wires together and tapeing them. I give you credit for trying to DIY and save money but really that O2 sensor from bosch is a piece of shit. I bet money if I hooked up a scope to that O2 sensor you installed and watched the waveform it wouldn't be in range. Hey it's your car though, if your ok with it great. Oh yeah before you get to happy that O2 sensor code is a two trip code, it doesn't just come back on after you clear the code. I would read up a little on engine performance before it bites you in the ass.
