Vacuum line.

Sent from my mind using the rusty stock leafs off my xj.

Where does it connect.

I dunno what year your rig is cause I'm on my phone but if yours is older it looks to me like the vaccuum line for the heater control valve.

Interior light problem: Check and make sure you headlight switch is not full over to interior lights always on.

You may also have a stuck door switch. Or tailgate not closing all the way. Or front or rear dome light switch set to always on.

How to fix?

.....this may be off... it may be a vacuum line... but does your cigarette.lighter work?

If you took that picture near the power distrbution box, it might be from the cruise control.

i found out where it went, not sure what it did, but its back in place,
