I have a 97 Cherokee Sport... I replaced the Cat O2 sensor with a Bosch Universal and I can't get the wiring straight. The new O2 instructions don't match anything like the Jeep side. (yes I know I should have wrote down the wire color matching before I cut the pigtail off) I have - Jeep side; Dark Brown, light brown, green and black............ On the O2 side I have 2-gray, black and white. I someone could look at theirs and let me know how they match up that would be great. I had done this on my TJ and didn't have this problem...
