I’m trying to repair my o2 sensor on the front manifolds wiring someone cut the plug off which I bought a new pigtail for but the new one has all white wires and the wiring on the truck is colored help please!!
Manda, You will need to obtain a wiring diagram and connector view diagram. The red and black wires should be the heater wires and the green and tan wires are your feedback wires. Your wiring diagram will label the four wires with a 1,2,3 and 4. The connector view will give you the corresponding location for each wire. Very simple once you have the diagrams. Good luck.
