d5n lgp dozer priority solenoid location?

[jrh7221]

i have a cat d5n lgp dozer with code 113--0697.06 which is the priority solenoid high. Also has a 3f and 3r code for the solenoids found location for those two but cant find location for the priority solenoid to replace it.
changed the alternator due to other codes it was throwing for low voltage. any ideas what else could be?
constant warning buzzer going off parking brake light flashing, and others flashing really fast.

A machine Serial Number would assist in obtaining technical information.
The Priority Valve is located beneath the floorplate in the operator compartment, mounted on the bevel gear case.
