What is this?

[Jeff Bottemiller]

My buddy and I have nearly identical RAM 3500 dually Laramie trucks. Mine is a 2015, his is a 2014. They appear to be equipped the same. However, his has this fuse cluster behind the driver side battery, mine doesn't. Does anyone know what this controls? Thanks

Does he have the factory aux. switches or the upfitter package? It may be that.

Factory aux switches

Thanks for the replies. I don't recall seeing any switches that I don't have but I'll check again.

More info: The truck is fully deleted (he bought it that way). It also has something plugged into the OBD port but I haven't traced the cable to see where it goes...maybe to this cluster. There is no tuner so whoever deleted the truck applied some kind of tune. I'm wondering if this fuse cluster is related to the delete...

The OEM up-fitter switchs will be next to the OEM trailer brake controller near the bottom of the center console.

Thanks for the insights. You are exactly correct. My truck has OEM assigned buttons for seat and steering wheel temp controls. On his, they are all AUX switches…5 of them. There’s no evidence that we can find as to what they control and we’ll have to do some research on how to program them.

Each one of the buttons corresponds to one of the relays. If I remember correctly there are options in either the radio or EVIC to for some of the switched to work with the ignition On or all the time.

Here is a video to help you with the auxiliary switch wiring. Can get a "Mopar wiring kit" that will help you. https://www.youtube.com/watch?v=GhahfEO7_5k

Thanks for the video...very informative. So apparently my buddy's truck has the switches but nothing has been connected to them. Good to know.
