Black is ground
Red is keyed power
Yellow is continuous power
I recommend adding a fuse in the red line if it doesn't have one. You can use a tester to locate keyed and continuous power sources. Connect the black wire to some metal on the chassis, scuff the paint so that you have a good bare metal connection.
