06 E350 auxiliary battery location
I have a 06 E350. I just replaced the main battery in the truck. Now I should replace the auxiliary battery. Where is it and how do I get access to it?
Thanks in advance.

It is located on the passenger side under the hood and below the cabin filter at the firewall.
Thanks for your help. I had the "Visit Workshop" light came on with the battery logo. I figure I might at well change it since the batteries are already 4-year-old. I really don't want to get stranded anywhere. Call it cheap insurance.
