License plate light wire

Awhile ago I had to replace the entire taillight wiring harness with the Fifth Avenue's, the one thing I wasn't sure of was/is what do I do with the license plate light wiring which as you can see has plugs for two sets of lights and The Cherry Bomb only has one set. Do I splice the wires to one plug or both? IMG_2023-04-08-23-12-21-740.jpg
