Spent 30 minutes and did the TPMS mod to get rid of my dash light.
In a nut shell;
1) Remove two screws from below the glove box.
2) Remove the 3 screws at the top of the glove box opening. Remove the connector attached to the glove box light.
3) Slide the HVAC vent to the left, then pop it out of the right side.
4) TPMS module is up inside the left. Black box about 4in by 4 in.
5) Remove the 10MM bolt holding the blue relay unit (seen in my picture) and move it out of the way. This gives your more working room.
6) Remove the 10MM bolt holding the TPMS module so you can swing the TPMS module down and towards you to get some working room. Bracket is located below the TPMS unit, just behind the other bolt you undid.
7) Unplug the TPMS sensor. Its on the back side as youd be looking looking at it, or the 9 oclock if you were sitting in the drivers seat.
8) Slide the wire loom down and locate the pink/grey wire. There is a pink/grey wire with a black stripe, make sure you don't pick that one.
9) Cut the pink/grey wire about 1in from the white connector. Tape the end off going into the white connector. Nothing else is done with this.
10) On the main harness side of the cut, strip the ends, and using either spade, butt or whatever method you want, connect a piece of wire and ground it to the nearest screw.
11) Heatshrink, tape or whatever you wish to secure and seal your connections
12) At this point, test your work. Plug the harness back into the TPMS module and start the vehicle. No TPMS light should be present. If it comes on, you probably either A) cut the wrong wire B) Grounded the wrong side of your cut.
12) Once you verified everything is good to go, replace the 10MM bolt holding the TPMS module.
13) Put the blue relay unit back in place and replace the 10MM bolt holding it in.
14) Put the HVAC vent back in
15) Put the glove box back together and enjoy not having your TPMS dash light on.
