OR VietVet Is Still Throwing $$$ at 2005 Z71

Last but not least. Choice of positive cable attachment. Inside/under the battery box or at the jumper connection?

I would connect the positive cable from the second battery to the same place where the positive cable from the first battery is attached. (In my case, it was the main fusible link on the passenger side firewall.).

The second battery install is all done. The disconnects are right at the second battery. The battery is the 2 year O'Reilly's Super Start and used 5 foot of positive and negative 6 AWG cable and tied off. The positive cable is attached at the Jump Start snap shut positive cable box and the negative is attached with another ground cable at an engine bracket. Tied off at the firewall and protected with 5' convoluted tubing for each cable.
