dual battery wiring and mounting help.

[Yendor]

Thanks mate do you mean the second battery or starter battery for the inline fuse? It will be bolted down in the back of the gq. Can you reccomend the best place to mount the dual battery controller in the cab?

What brand controller is it?

There's more room on the passenger side, either in the kick panel or even up behind the back of the glovebox.

For a rear battery installation I would recommend using circuits breakers, one mounted as close as possible to the positive post of each battery as well as conduit over the cables.
