I have a 2000 Dodge Ram 1500 I disabled the battery to replace a hose. When I hooked the battery back up the dome lights are on all the time but very dim and I can't get them off

You need to have the alarm reflashed, you lost the memory when you removed the battery and only the dealership can do this

roll down driver's window, put key in ignition, close and lock all doors, disconnect negative battery terminal, reach in window and turn and leave key to "on" position, ("on" position, not "start" position), reconnect negative battery terminal with key still in "on" position. This worked for me.
