Maintenance/Repairs

Hi, I have a 2005 jeep grand Cherokee that I just bought used, I noticed three blue wires running from the dash to the fusebox that I thought were weird, after doing research I believe they are hardwired to bypass a relay possibly or something like that. Two of the wires run to a switch that the previous owner installed to the dash that turn on the fog lights and the other one does not go to the engine fuse box but it goes to a cylindrical component in the engine that is right behind the headlight and wiper fluid reservoir, then the wire runs to another aftermarket switch next to the shifter, this button doesn’t seem to work. I also noticed that the daytime running lights constantly flicker when the car is on and the wiper fluid pumps do not turn on when switched on which I feel like has to do with the wiring issues with the fog lights possibly. Sorry for writing an essay about this but this jeep is my first car and I would enjoy some insight into what these problems are and possibly how to fix them, thanks.
