On the drivers side I have a green with white stripe,a solid green,a purple with white stripe,and a tan wire. Same wires on pass side but with a solid purple.

According to my schematics for a 2002, only the rear o2's have ignition hot pink wires. The front Bank 1 sensor 1 A-tan goes to a splice where the low reference wires are hooked together and also goes to C1-63, C1-25 C1-26, C1-28, and C1-29. It also hooks to A of sensor 2. The purple wires go to C1-65&66. The green wires are the heaters and go to C2-74&80.
