If you look at the passenger side of the firewall just above the battery, you'll see a small square of sound deadening, peel it off and you will see a hole to the passenger BCM area. Push a metal hanger with the edge bent over so you don't stab a wire and feed it to the BCM area, then tape the temp probe connector to it and pull it through.
Then you can stick the square material back over the hole with the wire and route the cable to the front of the car. I clipped mine under neath. The photos I originally posted is the way I routed it on my car but I discovered that hole later when running ooga horn wires. I routed the wires that way for Chuckdoc's car.
