Both your brakes are hydraulic, so any pair of wires at the levers, hand or foot, will be what you are looking for. A test light is your best friend, if you want to get really fancy buy one that you hook to power and ground. The one I use at work has a red LED to let me knkow it is powered, then when a touch a circuit it will lite a second one green if a ground and red if power. Sure keeps my DVOM in the box more often.
