How do I add aux switches

[Rammit2020]

I bought a 2020 Ram 2500 Bighorn and would like to add a few accessories but do not have spare aux switches on dash. What is the best site for replacement aux cluster? Looks like stock aux cluster has room for at least 3 more switches?

Not sure any one has upgraded a 2020 yet but you may want to check the AlfaOBD thread for starters.

Just FYI, it's a lot more then just adding the switch cluster. You'll need the relays, wiring, enable it in the BCM etc.

Not what you want to hear, but it’s a real pain in the wallet.

It can be done. You would get this lower switch bank to swap in place of yours-
Since you have a diesel, you already have the auxiliary fuse box in the engine bay because it is also used for the cabin duct heaters. You would just need to populate that aux fuse box with the rest of the relays, fuses, and wiring, then enable the switches with AlfaOBD.

Where would I find the aux fuse box under the hood? I have 2020 long horn diesel I didn’t see it.

It should be the one closest to the firewall, not the main one in front of the battery.
