I think you generically meant a tee. You'd simply use what is called a 6 port, 2 position diverter valve (or machinery selector valve), and place this after the directional control valve. Here is a $150 example that may be the exact part to use. In addition to this, you would need adapters to fit the hose ends, and a set of hoses to the second winch. Pretty simple. If not this valve, then another is ok, just make sure it is rated to a minimum of 25GPM and 1800psi. This valve just basically sends the fluid to the winch you choose. A tee would simply send the fluid to both at the same time, and it would take the path of least resistance, powering nothing. This one is a manual lever, but you could also get an electric solenoid version for about double the cost.
