Can I have multiple items wired into an upfitter/Aux

[PeceKeepr]

So I have 2 items I want to wire in. A 40” light bar using Aux 1 which is 15 amps. And in Aux 2 I want to use it for Rock lights. And that’s 10 amps. My question is can I use the same pig tail and just splice into the ground and having my positives going respectively to Aux 1 and Aux 2 thanks. Also another question in the future if I needed more power in one of the Aux switches could I just thrown I different size fuse in its place? Thanks, Brad

Yes to your first question. That is how it is designed. There are only 2 powered AUX plugs as far as I am aware so you'd have to double up at least one to use all 3 AUX switches.

As for your second question, theoretically yes, I believe they are all the same wire gauge so it should be safe. But I don't know if that's true for the entire wire harness. I looked at the AUX wire diagram a few weeks ago on TIS but I forgot to save it.

EDIT: I would personally be comfortable bumping AUX 2 and 3 to 15A but I would not go any higher.

I would never just install a larger fuse in any scenario. If you need more power than the circuit is rated for then always use a relay. They're cheap and effective and you won't risk frying anything.

Normally I would agree, however the AUX switches already use a relay. I would not bump it over the 15A without supplemental wiring though.
