Hey Mike, All my grounds are done the same way. Run two 8 gauge wires, one front and one back, then just tie all your grounds( lights, etc ) to that wire. Ground the two 8 gauge somewhere to the firewall, and also tie that to the engine block. Ground your battery to the engine block. You can also put a terminal strip under the dash, jump all the terminals together, then ground that to the the same place on the firewall. Now you can tie all your small grounds ( radio, gauges, etc. ) to the terminal strip. Use at least 8 gauge for your main power feed to the fuse box. See if you can download the wiring diagram from RF.
