Just run the wires from under the hood to one of the rear bats. the link all rear batteries together. As for the ground, what i did was run ground wire from front batterie to one of the rear ones.

i think most of em run under the car and cover the wire with protection

i wonder if you could use a buss bar to ground all of them to one ground

thats what i was gonna do, run a buss bar for power under the hood and a buss bar for the grounds too.

Also would a batt.. isolator help me or hurt me?

and would a high farad cap help me any? like 20 farad?

Isolators cause a voltage drop. Not worth it.

Don't bother with a capacitor either.

As for the multiple runs, I had to modify my firewall a little bit to get all 4 runs through. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Ground the rear batteries to the front battery.

my 4 runs were easy. i just went under the firewall and then came up like this.
