Parking switch above steering wheel works with ignition turned off or on. Check this first.
PSUP02 Battery + to A PSUP03
PSUP03 A to Fuse 7 to L PSUP04
PSUP04 L to FB12 to ILMES01
ILMES01 FB12 to PK SW ON to PK SW COM to FB3 Parking switch ON
PSUP04 FB3 to Fuse 5 to FB6 and FB7
ILMES03 FB6 to front parking lights to ground
ILMES03 FB7 to rear parking lights to ground

RPG,
I tried ohming out this circuit because nothing turns on with the parking switch above the steering wheel. Even with on and off I get a beep from FB3 to Fuse 5 or essentially FB3 to FB 6 or 7. If the switch or wires to the switch are function when the parking switch is off I shouldn’t get a beep correct?
