Upfitter Switches
I have a 2019 F250 XL. I’m wiring in a strobe light and it seems that the key has to be on for the upfitter switch to work. I’ve read that on some older models you could move the 5amp fuse in the fuse box over and make some of the switches work without the key on, however on the 2019 there isn’t a spot to move the fuse over. Is the any way to make the upfitter switches work without the key being on?

I think it’s in the OM but this will be a little more detailed.
