Curious about your back blade with lots of hoses on them and a black box? Can you tell me about it? I’m looking to do mine on a single hydraulic cylinder to make angled adjustments from the seat.
I have three rear remotes;
one goes to the hydraulic top link,
one goes up to the front to angle my front blade or run the grapple,
just leaves one open for the rear blade.
One set of remotes it goes to a diverter valve (have a second one to stack together),
have a toggle switch in the cab double pole double throw wired to a 4 pin trailer connector (round),
that flex cable runs to the junction block (black box), when the switch is in the center position (off)
hydraulic flow is straight thru the diverter to angle cylinder, switch up hydraulic flow is to the tilt cylinder for the blade,
when I add the second diverter and an offset cylinder, switch down will direct the hydraulic flow to the offset cylinder.
Just a way for one set of remotes to handle multiple cylinders.
Baileys calls them selector valves;
VALVE SELECTOR VALVE 12 VOLT DC SAE 1 WORK PORTS 3625 PSI
When de-energized flow is straight thru, when energized flow is thru the other ports.
One provides two different hydraulic circuits, stack two and you can have three, stack three and one remote can handle four different cylinders.
The black box is just a trailer junction box for the wiring to go to and stay some what neat and protected.
