Cargo light wiring / switch

[mompracen_bs]

Good morning, For Custom (2.0 engine).
Has anyone added ‘switch style automotive’ 3 position ON/Auto(light with door open)/OFF for the cargo area rear lights?

Does anyone know if the wiring harness for the cargo area right/left lights are separated already by the fuse box ?
Or do they split average zone-plate (plate between seat and cargo area)?
