I did mine yesterday. I went to where it taps into the ECU under the passenger carpet. It is the wire going into pin 88. It will be on one of the outside rows. You will see numbers on the ends. If memory serves me correctly the first number on the last row is 79. Find that one and count up to 88. I believe it is a green wire with a black stripe. Don't quote me on that one though. Hope this helps and good luck.
