so if you hook up to the wires under the hood do you have to do anything in the glove box then?

The circuits for each of the 4 Upfitter switches are "open" as your Raptor is shipped from the factory. There are two breaks in the circuits:

First break (1): The wires from the Upfitter switches run to the area behind the glovebox and end there. There are other wires that run from that location through the firewall to their termination point above the passenger side wheelwell.

Second break (2): The wires that run through the firewall and terminate above the passenger side wheelwell need to be connected to your lights and/or accessories.

You'll need to close the circuits in these two locations. You'll need to connect the wires that run from the Upfitter switches to the area behind the glovebox to the wires that run from there to through the firewall terminating above the wheelwell.

Once you connect these two sets of wires (per the instructions provided earlier in this thread) your work behind the glovebox is done. Then you can connect your lights/accessories under the hood and you should be good-to-go! :thumbsup:

Thanks for the thread, just wired up the last of my switches. I did one awhile back, but while I was in there this time, only needed one more, decided to do them all.
I removed the glove box completely and then also the bracket that all the wire harness connectors are attached to. I slid the connectors off the bracket and then removed the bracket, made so much more room and this a lot easier than the first time!
