Where are the wires for the upfitter switches on a 2010 F250?

I need to wire a fuel pump to the upfitter switch. Do they run the wires through the firewall? Are the first two switches 30 amps? Thanks!

wire locations and colors are listed in the book...plus the amps.... through wall wires are bundled up at the fire wall behind steering/brake hydro pump...back drivers side

Believe the first two (1, 2) are 30 amp and the last two (3, 4) are 10 amp.

So are the wires easier to reach from the top or bottom?

i think 1 and 2 are 30A #3 is 10 and #4 is 15 i believe.

The wires are bundled up by the parking break. there are also pass through wires that run through the firewall and come out the top drivers side of the engine compartment.

top.... for the fire wall engine compartment.....remove trim panel below steering wheel to access up fitter switch wires.. wire pump to the firewall through wire.. find corresponding end up under dash, wire to desired upfitter wire and you are done...these wires are capped with black shrink tube..
