Moving positive lead of Upfitter distro box

[mmerzke]

I have a 2024 Ford F250 Tremor, and it did not come with the dual battery from the factory. I have however installed one and connected it to the starter battery via a Redarc smart battery isolator. I would like to power any lights or accessories I add with the second battery instead of the starter battery.

Can I do this by moving the positive lead that is currently attached to the bus bar off the starter battery and running it to the new battery?

Or do I need to have use the current upfitter wires to new relays and then have those new relays attached to the new battery?

I’m assuming it is the same bus design as my ‘22. There is a single positive lead bolted to the bus bar that powers the entire upfitter distribution box. Should just have to pull that and transfer it to the other side of your battery isolator.
