More trailer questions please.

what i would do with the clearance lights is just take a length of your old trailer harness and use that only for the clearance lights. make the connection up at the tongue where the 16/3 starts. for that i would use a yellow heat shrink connector because you can put 2 16 awg wires in one side (for clearance lights and running lights on the trailer side) and on the tongue side where your using the old harness just strip back twice as much as u normally would and fold it over and then crimp it down. i hope i explained it so its understandable. i can get some pics if you need them. let me know.
