After the hassels with prior toad lighting and diodes etch. When I got my latest toad I checked out the space in my tail lights and found enough room to drill a hole from the trunk side into each housing and mount a new tail light socket that houses a tail light and stop light double bulb and ran a wire harness under the car to the connector fitting mounted below the license plate in front. The usual bus to toad cord with connectors Camping world sells this system as one of their choices. It's been working well for a couple of years now.
