UPFITTER SWITCH

Have a '13 F350 Lariat with factory upfitter switches. I want to use one to power aux power for GPS, Dash cam, etc so it is only powered when the ignition is on. Perfect application, right??

I am wired to the Brown wire. Ignition off - no power - good. Ignition on. I get only about 5V?? ?? ?? And nothing works?
Regular 12V power outlet reads 12V all the time.
HELP!!

I'm assuming the wiring is the same for the '13 as my '15...so this is all I have to go off of. The upfitter switches aren't all the same. Switch #1 and #2 are 25 amps. #3 is 10 amps, and #4 is 15 amps.
Wiring colors:
#1 - Yellow
#2 - Green and Brown
#3 - Violet and Green
#4 - Brown

Nevermind the red circles. Just pay attention to the relay wires coming out at the bottom.
