Yes it is easy. Lift the playfield and remove the bracket that holds the coil (two screws I believe). Cut the wires from the existing coil and and solder the wires to the new coil. Place it back into the bracket and screw the bracket to the playfield. I did it so anyone can do it.
Nut driver (to remove bracket)
Soldering Iron & solder
Possibly phillips head screw driver (for smaller bracket attached to larger bracket)
Edit: No need to raise the upper playfield as the bracket and coil are under the main playfield.
