            What does the one under the dash look like? there is a big white connector box under there, looks like it could be part of that but im not sure. I've got the connector from the wiring harness sitting under there so I don't want to go running unneeded wires.

              There should be a 2 conductor white plug that connects to the old OBC (if you had one) if you only had the clock, then you may have to run a wire to the front of the car...

              That connector is located in the main harness that is to the left of the ABS Computer, you should see it tied up there..

                  Find the drivers side foglight wires. Follow them back up to the harness. The connector for the temp sensor should be right next to where the foglight wires disappear into the main wire bundle.
