I installed a tilt/rotator/auto lock to my 080-3 excavator. The factory installed an A & B hydraulic feeds to the end of the boom, I need 3 hydraulic feeds.
Using a hydraulic diagram of the 080-3 hydraulic pump(which I can’t seem to locate); is there a spare hydraulic feed that I can use to feed an additional hydraulic feed to the end of the boom? Or do I have to install a dual 2 sided proportional valve and split one of the hydraulic line that are already there?
Thanks for your help

Thanks for everyones help. with your help, This is how I made this work.
I purchased a Hydraulic Solenoid Selector/Diverter Valve, 13 GPM, 12v DC 3,650psi, 2 lines "in" and 4 lines "out": (which is somewhat the direction suggested by PoTreeBoy). I made the purchase from Summit Hydraulics.
The valve's normal open position "A", meaning when the excavators AUX 2 is "ON", the valve will always have pressure on side "A" "out". When electrically activated (momentarily) the valve switches to the pressure from side "A" out to "B" side "out". When electricity is deactivated, the spring load valve switches the valve back to pressure side "A" "out". This relates to; Side "A" will always have pressure unless; you push a button or select a switch position position "B", the diverter moves the hydraulic pressure from side "A" to side "B". Let off the switch or toggle the diverter automatically sends pressure back to side "A" out.
Next: I ran one 12VDC lines from the cab to the base of the boom. One 12vDC line will run the diverter valve ( as described above).
The four lines coming out of the diverter are connected as such:
I want the tilt function to work all the time, so I connected the tilt function to the AUX 2 port (normally open).
I then ran the two hoses from the "B" side (normally closed) and (momentary activation side).
I then connected the two hydraulic lines to the hydraulic auto hitch.
From the dash, I then mounted and wired a three position select switch in the dash to the diverter valve. the switches position "B" is wired to a relay, powering the DIN on the diverter valve to activate the solenoid to change from side "A" to side "B" activating allowing the momentary flow to the hydraulic auto hitch activation.
I also installed two position momentary safety switch, which has to be depressed when operating the momentary hydraulics on hydraulic auto hitch (side B). If the safety switch is not pressed the auto hitch operations will not function.
Depending on which side you select side A or B you can run two hydraulic feeds off of the excavators AUX B using the joy stick.
