I tried to change my clock out two weekends ago, and couldn't figure it out. The knobs are connected to manual translators and I had tons of trouble making space. There was a plug back there that stopped me from getting the old clock out. After hours of fighting I cleaned everything I could and stuck it back together. I am at a loss with this part. Wish I could help more but that part, and the lower dash, are my biggest upsets on my car. Good luck
