It wouldn't let me post in the mods section yet
I recently installed an after market header on my sentra 02 1.8 5spd and it only came with 2 o2 holes I was wondering if anyone has done the bypass on this model for the other two and if so I need help on what to wire in to get rid of the CEL my inspection is coming up soon

most people will drill the extra holes and add bungs whereever they are needed. but there are other ways around this, unfortunately, they involve soldering and rewiring. hopefully someone with a 1.8 will chime in. you can do the pedal dance to clear your ses codes, but you may not pass inspection unless the systems on your vehicle are 'ready'.

That what I was looking to do is soldering and rewiring I am just not sure of what resistor to use or what wires to solder I was hoping someone else has done this I believe it's bank 1 sensor 2 and bank 2 sensor 1 that need to be rewired I can check with my code reader if it makes a difference in the procedure

im not sure, as i have the 2.5L, which only has 2 o2 sensors. hopefully someone knows what to wire in for you, also hope they will chime in. normally, you would just put some anti-foulers, or spacers, on the lower o2 sensors, which is much easier than rewiring. but in your case, you have 4 o2 sensors. have you tried searching the site? use the 'search' button in the blue menubar. you can also search google or something as well. you will be looking for something particular to the 1.8L sentras, as the 2.5L sentras have only 2 o2 sensors. i know the question has been asked in the past, many times.
