bobcats rear aux solution

[buzzsaw]

I have a problem dealing with rear aux kit. bc is way to expensive and basically the kit doesn't work on the new m series machines when we trade. so instead of spending 1500 and throw it a way im thinking of putting a splitter on the aux hydraulics then coupling them to the out side of the machine. my ? is if i have bc turn on the rear aux can i tap into the harness and use the controls on the handle. i thinking when you flip the switch it should send 12 volts to the solenoid will this work?
