Hello Homer, thanks for reaching out. We do offer a wiring harness for the 2026 GMC Terrain Elevation without the factory tow package. For that you will need the following:
- T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # TK68DR
Are you needing to add a trailer hitch also? Or just the wiring for now?
