My 02 sensor fell out and I need to splice the wires since the clip is broken from dragging on the ground.

Does anyone know the order?

From Harness: black, white, yellow, red
From rear 02 sensor : blacl, blue, white, black

(I can tell you what the 97-99 has. 95 is probably the same.)
Harness side: Red and yellow (red and yellow/black for rear O2) are the heaters. White is signal and black is signal ground. The connectors are different and have different pins.
Sensor side: Every after market O2 has different color wires. If you have 2 same color wires, they are usually the heaters (go either way - they measure about 12 ohms so you can easily find them even if they are not the same color). The other 2 are the signal and signal ground wires. If one is black it's usually signal ground (so the other is the signal). If that doesn't work reverse them.
