Bought a 2005 Jeep Liberty recently and have a few mysterious wiring and sound system modifications that continue to cause problems. The car has: a Blue Ox tow plate installed with a standard wiring connector time the RV A Brakebuddy classic braking system with standard wiring connectir Two power amplifiers for the sound system. Can’t tell if they are working or not. A relay custom connected to the interior fuse panel. See picture attached. After cleaning up all the connectors to it I was able to get the low beams working. The instrument panel lights still don’t work. The overhead interior light is always on and the drivers floor light is lit at night when the headlights are on. wonder why the custom relay was installed. It’s a VF4 85F11. Any ideas what might be going on?
