I have a question. Im new to this Tahoe forum and I been seeing people say G3,G4, or G5. What does that mean? What would I have to do to get a harness from you for my 2007 Chevy Tahoe LT?
G3, G4, and G5 are not OEM. They are aftermarket LED tail lamps. They do not require a harness.
Only the OEM tails will require a modified harness.
