How to make upfitter switch work with no key

[johnny9r]

Does anyone know if you can make the upfitter switches work when there is no key in the ignition? I would like to wire some things up that I want to work when the truck is off.

Your going to have to find the power in wire and run a fused wire from the battery to that wire.

Take out relay # 305 in fuse panel in dash. Take short piece of wire and crimp a male non insulated spade connector on each end of wire. Insert one end in the opening for the # 87 post on the relay and the other on in the opening for the # 30 post on relay

Will this give power to all 4 AUX switches all the time?

Now we need the way to get power to the trailer without the key on.....

It would be nice to not have to turn the key on to use the switches. Just wondering, Does relay #305 only control the upfitter switches?

I found no relay #305. I found a relay in location 48 in the pass. kick panel but, nothing calling it #305...

The 08 upfitters don't use a control relay like the 05-07's, they get power from the smart junction box so you would have to cut the power wire and add a new wire with a fuse to a full time 12v source. It looks like it is the solid green wire feeding the upfitter switches.

Here's the upfitter diagrams, just scroll down for the 2008 diagram: https://www.fleet.ford.com/TRUCKBBAS/non-html/Q117.pdf
