The Max-Bilt kit includes these really cool waterproof solder-filled heat-shrink connectors. All you have to do is strip about 3⁄8-inch from the wire on the Jeep side and the wire on the light. Put both ends in the connector and heat it up. I prefer to unplug the old taillight and then cut the plug off of it so that the new lights unplug like factory. The kit doesn’t include a license plate light, so that chrome thing is a license plate light from a local parts store to keep things legal.
