Well i though with a little research I could find out what these are but the only thing I could come up with is that one of the wires is for an in bay work light.
The first picture is what I'm most concerned about because the hose that is shown attached was not attached this morning. I'm not sure how long it has been that way. Here they are. Oh and the second and third pictures are of the same wire

1995 XJ sport 4.0

 

here the disconnected hose and it runs to the rear where it has a Y connection that goes to the fuel tank.

 

#2 and #3 look like they go to the underhood light.

 

Thanks thats what I was thinking.

 

picture 4 is located in front of the engine coolant bottle behind the battery.

 

#1 Is the AC acumulator




ps next oil change get rid of that fram oil filter for a FL-1A motorcraft

 

well i didnt see this post i dont think the acumulator would go to the fuel pump so scratch my previous post

 

Well i'm %99 sure its my evap. canister. So whats its purpose?? I know it has to do with emissions, but will that being disconnected and reconnected make a difference? I heard it can make idling rough.

 

The carbon cannister captures and stores engine gasoline vapors to be burned in the engine.

It is part of emission control. It helps keep gasoline vapors from the fuel tank venting into the atmosphere.
