If you can track down the TPMS section of the service manual or at least the instrument cluster electrical wiring diagram, then I can tell you if this method will work. As far as location goes, the EPC shows a very poor representation of the location, but I think it is showing it as being behind the lower part of the C-pillar cover.

Now I am a bit confused about that. There was no 2007 Scion xb. 2006 models ran late, and they didn't introduce the new style to 2008.

Let me see what I can find out about the wiring diagram. Shouldn't be too hard to come up with. I'l probably just buy a service manual. It's the only car I have never bought one for. Thanks.
