What's the best way to run dual batteries? I'm gonnna run them in both my Grand and my Wrangler. My wrangler will need them for winching and accessories, and My ZJ will just need it for accessories and as a utility truck. It will also be my DD. I'm back in school and broke. I'm all for building things myself. I prefer it. I just need a "jump start" (hehehe) in the right direction. I'm about to start an electrical course at school but I'm still very ignorant. Help a guy out? Thanks
