Hey everyone, seeing a lot of nice write ups on this conversion but just looking for a little additional advice on this as I’m almost done piecing it together. I have a 2021 Silverado 2500 Z71 midnight with factory LED. I have the 2025 headlights, headlight harness from Gen5, Facia and LTZ grille My new oem bumper came with a pre installed harness for sensors / fogs etc, does anyone know it this main bumper harness plug mates with the existing 20-23 harness? Also are there any issues with the active grille shutter frame? Some write ups I read say to install an upper shutter frame from a 24-25, and some say you don’t? Any input appreciated.
