There are mating plugs with crimp on terminals to replace the connector attached to the front door. The kit comes with a "pin map" to follow in assigning the door connector wires to the cavities in the two round plugs. There is a twist lock cap for the 19pin plug for use when the door is disconnected to protect the contacts as some of them have constant voltage to them. Common tools and and crimping pliers are all that is needed to convert the Jeep's door connectors.The best thing about this mod is that it is reversible very easily. The price is per side.
