The two H11 plugs (circled in the picture), plug into the angel eye drivers on any angel eye kit purchased from us;
The red wire goes to the power battery terminal on your care;
The black wire goes to the ground (black) battery terminal on your car;
The fuse goes to any switched fuse terminal on your car.
“Switched” means the fuse terminal will not have power when the ignition is switched off, and will have power when the ignition is switched on. If you are not sure which fuse on your car is switched, simply turn the car off, plug in the harness with the rings connected and try different fuses until the angel eyes do NOT turn on.
