Changing out auxiliary battery in my wife's car. Wiring will be installed next week at the shop.

Quick video to replace an auxiliary battery in a CLA 250. Car was displaying a malfunction.
I needed the guys to install sealant at the shop (roof) before electrician can get all wiring done. Now it's time to pressure wash the entire shop and get the wire installed. I'm going to look at one more truck in 2 weeks as well.
Stay tuned!!!
