Micra K12 (C?) Wiring Harness

Hi there,
I have the Clarion CY00E stereo in my 58 plate micra k12, I purchased some wiring harnesses that were meant for this car as I wanted to upgrade my stereo to a pioneer sph-dab20… but the harness doesn’t fit, I have the facelift version of the car where the screws aren’t visible to remove, does anyone know what wiring harness I need to be able to do this?
