Someone probably had a bad one and just put a plug in.

 

I haven't been able to keyword search online to find a new one, the only one I see is the one for the trans oil cooler. EDIT: Found one.

I LS swapped the rover and drained the transmission during the process. The car starts and runs fine. It has a new battery. I discovered the p0705 and flashing M&S during start up when i started doing the trans fluid refill process (after I cold filled to the bottom of the fill plug) is it possible this issue goes away after I finish filling fluid? It did grind when I shifted through all gears and back into park while Idling. I've now removed the XYZ switch and opened it up to clean but mine is the version with the micro switches not the contacts with copper tracks.

 

Reinstalled the XYZ switch after cleaning it and its connector. Problem went away after I repositioned the switch and got my PRNDL indicator lights back. Now I'm fighting the T case neutral switch which has begun flashing and chiming. I am able to shift through low, neutral, and high very easily and Ive done it a few times in motion and static in neutral, but the chiming continues. Maybe I swapped the switch plugs, I dont think so though because I'm pretty sure theyre all unique shapes. There is also no associated DTC maybe the switch has gone bad so it doesnt know which gear range its in.
