Xyz??

its a mechanical switch that sits on the side of the transmission. tells the tranny ECU what gear the transmission is in and lets it display it on the console. It has a rubber gasket that fails because an AC drain drips on it. It then fills with old water and dirt the contacts become soiled and no longer work properly and the signal is a mess throwing the truck into limp mode, where you get only 3rd gear and the M and S lights blink at you. if the contacts are not that rusted you can go in with some electronics cleaner and clean all the dirt and mud out , reassemble, reseal with silicone, and it should last another 10 years.

the truck will start without the xyz in working order. It will instantly go into limp.
the safety neutral switch is in the middle console and keeps the transfer case from shifting from hi to lo gear without the tranny in neutral. It also can fail and keep you locked in hi or worse lo.
the brake light switch can keep you from getting out of park and into gear.

Okay. Look at a picture of the neutral safety switch and look at the picture above. If it's not the neutral safety switch, it must be it's long lost twin brother. The way accessing it is described, it sounds like it puts you right under the console (exactly where the neutral safety switch is).

I hope this worked. Never posted a picture on here before.
It didn't work, so here's a couple links:

Even though it's a different angle, it sure looks like the picture above, and the rest of the world calls it a neutral safety switch.

not sure you understand. The XYZ as we call it in America or WXYZ as it's known in other markets is located on the side of the transmission attached to the shift cable. Yes in other cars it is referred Neutral Safety Switch. However on the Land Rover Discovery we already have BOTH a transmission AND a transfer case Neutral Safety Switch therefore the transmission is referred to as the XYZ or WXYZ and the transfer case is simply the Neutral Safety Switch.
Let me google that for you
