Important: Don't rely on generic harness labels alone. Each GM vehicle has unique wiring configurations, even though this harness is compatible with hundreds of GM models.
We strongly recommend obtaining the factory wiring diagram specific to your exact vehicle year/make/model. The best resource is acdelcotds.com/subscriptions - their 3-day membership gives you access to official GM wiring diagrams, which will ensure proper installation of this DIY harness.
Having the correct diagram will help you identify the exact wire functions for your specific vehicle and avoid potential installation issues.
Thanks for bringing this up!
