10 minute job, with no cutting or drilling needed, though most cut the original wires and crimp spade terminals on the ends.
If not you could use bullet connectors to fit the ends of the wires leading to a short wire with a spade one each end, if you did not want to cut.
Connect up two wires to coil, secure in place of old one, it even fits on the std screw holes as the group a has elongated slots.
The + and - are between the terminals in the gap between each pair, took me a few mins to find!!
