DoubleD is correct. I have found the wire that actually goes to the TPSM itself but it is not labled with any given wire other then the fact that it attaches to one that controls a lot of other stuff. In regards to the fuse question you can disable it by simply pulling the cluster gauge fuse but then that would make your cluster to stop working which isn't worth it in my book. So I guess Nissan went a long way to make sure that this wasn't tampered with. So you will have to deal with the light on and alarm going off.

Also the monitor measures all of the tires when they are in motion as previously stated by someone and that's the reason that in your owners manual it says not to have any kind of antennas mounted on your windows as it will interfere with the signal getting to the monitor and will cause the monitor to malfunction.

Edited to add: If you have the ESM then go to the DI part of the electrical section then go down to either the combination meters or the warning lamps for the schematics. There you'll see the listing the for TPSM but there is no wire number showing.
