Move the heated bed close enough to the printer that the wires will reach the pads that you have tinned.
Fan out the exposed strands of wire for the 12awg red and black wires. Solder them to the heated bed in the location indicated ( The - pad and the 2+ pad)
NOTE: You may need to increase the temperature of your iron. These are large wires and pads. The large pads will pull heat away from the iron very quickly. Ensure that the pads and wire strands get hot enough to wick the solder throughout resulting a good solder joint. Apply additional solder as needed.
Bridge the two solder pads as shown with the red arrow. DO NOT BRIDGE ALL THREE TOGETHER.
