Good quick harness connector!

Worked fine for my truck! It fitted right in in the factory connector of my 2004 Tahoe LT no onstar non amplified system! I lost the door chimes sadly but it didn't matter much for me. No issues with battery drain or things like that. If you'd prefer not to buy the expensive harness for your 2003-06 Tahoe/Suburban, Or GMC Yukon non amplified, and no onstar, but don't really care for the door chimes, this one is the one for you! Remember, it has to be the non amplified system. If you have the Bose amplified system, this harness will not work for you, you'll need the special one. Hope this helps anyone who's looking to buy this harness for their 03-06 Tahoe Suburban or Yukon truck. Prior to purchasing the harness, I read the back of the package saying it fits a Silverado / Sierra from 03 to 06 and 2007 Classic so I assumed they were the same

Easy Product

Could be user error but it isn't working, could also be the radio. Overall easy to understand product though. Tells you what colors are which.
