    Converters stolen..straight pipes installed. Need pin out diagrams for downstream O2 sensors.
    Hi everyone. New to forum and looking for some help. Some jack wagon stole both of of my converters on my 02 Tundra and sheared off the downstream oxygen sensors as well. I’m looking for a clear and simple wiring diagram for both downstream sensors, with color codes and pin outs. Can’t seem to find a good print online for my truck. I have the pigtails that must be spliced into the oxygen connector on the main harness..just want to make sure I get the 4 wires connected properly. The pigtail connectors are aftermarket, and I have two new Denso downstream sensors.
