Battery temperature sensor. Yes you need it. It's commected to your PCM and you'll get a Check Engine Light without it.

Sounds like 96+ XJs. My 91 doesn't have that one, TG. That's about the only useless XJ upgrade mine doesn't have....

My tray was just a piece on flat metal bent to fit with holes in it. Either some PO had takin it out or it was some where else but it want on the tray.

I wish I had pics to show but I never thought to take pic of the tray.
