I have a little favor for someone . I had a coolant leak last year and replaced the radiator. Some coolant was on the 02 sensor plugs and messed it up. connectors were all broken. dry rotted. So yesterday I finally touched it and all crumbled. So the 4 wires coming from the wiring harness looks like white, brown,black and purple color. 4 Wires on 02 sensor. black black blue an white. Any ideas where to find out where the wires connect. please answer here or maybe email. jonathan1551@msn.com thank you so much guys.
