does it require professional help changing the battery wires?
What is involved with changing battery wires on 99 Bonneville se 3800 v-6? on 1999 Pontiac Bonneville
No, it doesn't have to be a pro but someone with some car savvy!! Find a friend that has that to help you out....it's not rocket science or anything, however if done incorrectly can cause a lot of damage to the vehicles electrical system!!
