Sporster Trike Tailights wiring

[OldmanLI]

I just picked up a 93 Sportster that was converted to a trike it is a great low mileage bike that looks and runs great and she loves it. My only problem is that the taillights on the fenders are wired for the running lights and brake lights the turn signals are located on the aft body of the bike which can be seen in the picture. These lights are not very visible and she wants them back in the taillights. Does anybody have any wiring diagrams or ideas how I can rewire the lights so that the turn signals will be in the actual taillights?

HD has a dealer kit to eliminate the center brake light.
The brake, night running & directional use only the two side mounted bulbs,
similiar to a trailer set up.

U Haul has a wiring diagram for trailer light setup.

The two center most upper lights could be eliminated or two light on each side wired in parallel. However, All bulbs need to be two filaments.
May have to change out the bulb sockets.
