Information on changing the control pattern on a John Deere 120

[N8twny]

Hey, does anyone have any info on which lines to change or where at on a John Deere 120 excavator to change the control pattern I have a couple pictures I will upload of behind the cab with a couple blocks of hoses.
Thanks, Nate

If I was a betting man I would say the (2) rusty Parker -6T solenoid valve blocks are for a control pattern selector kit. The electrical switch controlling the kit would likely be in the panel just behind the operator seat.
See screenshot below from the Deere parts site. The same diagram should be in your parts book as well.

Thank you, Diesle Dave. I will look behind the seat tomorrow or Monday and let you know what I find.
