If anyone else is looking to do a dual battery like mine, below is a link to where to get a much better solenoid than the one I have and it's cheap. Mine is only rated for 85a continuous and this one is 200 cont, 400 surge. I'm ordering one since I think mine is crapping out from running the winch across it.

Hey Tom you got any pictures of where your second battery. And how did you wire yours in. My intentions are to put a second battery in the bed and ground it within a foot then run like a 0 guage power wire directly to the original battery and maybe beef up the wire coming from the alt that be overkill.

 

If I remember correctly, Tom located his second battery under his K&N Air Intake FIlter. I think the cone was changed to be a longer, narrower filter to allow room underneath for the battery.

How he hooked it in, I don't know. :D

 

ohh okay... that would be sweet to have it under the hood

 

Nah, less weight in the nose is preferred, but it would be a PITA to run all the wiring into the bed.

 

There are pics plus a schematic and brief how-to at: http://www.tombarcia.net/Truck/DualBatt/index.html

Swoop is right, I had to use a long and narrow cone filter and a narrow Optima battery. I believe that the Optima part number is in the how-to.
