After doing the Ranger header swap, my o2 sensor connector wouldn't reach the connector in my car. I tried to cut the connector off (the one off my car, not the one coming off of my o2 sensor)and splice in about 6 extra inches to each wire so the connector would reach. But I lost some of my wire splices, so two of my wires wouldn't connect. I bought a Bosch universal o2 sensor and I now have plenty of reach. I know what wires do what coming off the new sensor, as a chart tells what each does. I can not find any wiring diagrams telling me the function of each color wire that comes off of my car. I need to know which wires to correctly splice together. The motor continuuly stumbles, and am afraid to take it out on the hwy. Could not having the egr hooked up be part of the stumbling problem? Thanks for your help.
