2011 ram 1500 cigarette lighter fuse Fuse: Locations — Dodge and RAM Truck 4WD V8-4.7L Service Manual 2002-2008 Dodge Ram 1500 Fuse

Be very careful not to confuse the two sockets, especially if you're using say a 5 amp fuse for the new accessory and the OEM fuse is say 20 amps

So, I decided to take the time to label each fuse location for future reference

BTW you should check all the fuses if they are fitted tightly as they may be loose from the manufacturer.Please see the picture attached to make it clearer

so you can utilize the cig lighter plug at all times and not just when the truck is on.

The fuse for the cigarette lighter is located in the fuse box, which can typically be found either under the dashboard near the drivers side or in the engine bay
