I have a 2006 jeep grand cherokee laredo 3.7. Wiring for the O2 sensor (bank 1, sensor 2 I believe) was damaged (not the O2 sensor itself but from the wiring harness) and I've looked for hours to try to find the correct colors on it with no luck. Couldn't find a replacement connector either. Ended up just ordering an extension and using that for a replacement but of course the wires are different colors and I'm not sure which ones go with which. Replacement wires are red, black, yellow, and white. Any ideas so I can get back on the road?! Thanks!
