i went with two relays (big fuses basically) and a battery isolator from stinger. i also got the battery tray from gm, notice that they do NOT make a hood brace for it with the tray. i used 0 gauge wire for all of my runs, until the distribution block to my amps. then it is 2 gauge.hey mike how did you do your dual battery setup again? What parts would i need to do this?
i got the battery tray for cost...i believe it was around 30 bucks.Do you have a link to the isolator you used? And how much was the battery tray? I think you can get them from ckresto for $30. I took the hood braces off my truck already. It didn't seem to hurt anything. My buddy's hd doesn't have them from the factory and he has the second battery there also.
