I have a 2008 Yukon Denali That I am wanting to pull all the interior, including heated leather seats and the Bose system and drop it in a base model 08 Tahoe I own both vehicles. I thought everything would just wire up with the factory Tahoe harness do I need to completely rip out the body harness for the Denali and install it in my Tahoe? I know trying to get into these dashes will be a nightmare.
