Power Distribution Box

[BLUKTY2]

Truck is a 2017 3500. There is a power distribution box on the left side of the engine compartment just behind the battery near the firewall and on the opposite side of the battery from the main power distribution center. It contains only relays and what I think are circuit breakers, no fuses. There is no mention of this box in the owners manual that I can find and the inside lid of this box does not have a list of what circuit each of these relays and circuit breakers control (unlike the main power distribution center). A fairly quick online search pulled up nothing related to it. Can anyone provide me with this information? TIA!

Do you have auxiliary switches under you a/c controls?

Yes I do. I see where you are going with this; these are for the aux switches? Here are some photos.

Thank you for this link but I watched it a few times many years ago as I was wiring my selected accessories. It does not explain what the power distribution box in question does, and this is the information that I am looking for. Thank you all for the responses so far!

the power distribution is the outputs that activate when the individual auxiliary switches are used, the 4 wire plug on the left should be the output leads for offroad lights or other 12v accessories.

It's just relays for your Aux switches.

Thank you, makes sense. It would be nice to know which relay is associated with each switch but I should be able to figure it out.

I finally found the information that I was looking for, so I thought that I would share:
