Hey Harold, thanks for reaching out!
The difference between the Curt Wiring Harnesses for your 2018 GMC Terrain is that the part # C56375 comes with relays that you install in your vehicle fuse/relay box while the part # C94FR (56429) has plugs integrated into the wiring for those relays.
They install using the same plug and they give you the same functions so it just depends on where you'd rather install the relays at.
