These parts should cost you about $116.00, it looks stock and you will should never have another battery issue. I have schematics but you can not really see much, e-mail me at carl@hcvind.com and I will send them to you

I have a 2005 EscaladeESV and would like to add a second battery. Is the physical space proximal to the firewall on the passenger side substantially greater in the '07s and following than previous generation Escalades? My concern is less with wiring specifics and more with obtaining a 'mounting tray' and brackets to secure an Optima Yellow Top.

I've plans for using the deep cycle Yellow Top in isolation from the main battery while using the ESV as a "Motor Home" i.e. parked overnight with separately powered auxilliary internal illumination. Am considering using the following to isolate the secondary battery while the engine is off, thus keeping the main battery untouched:
