Lost the 02 sensor wiring harness connector
kind of a dumb question, but here goes. After putting the trans back in, and rehanging the exhaust, I was able to locate the connectors out of the main wiring harness to plug in the driver's side front and back 02 sensors. However, I cannot find where I am supposed to plug in the passenger side 02 sensor. Does the plug come down from the passenger side of the engine compartment? Where should I be looking to find this? the truck is a 2003 XLT 4WD with a 4.0. Thanks.
