Trunk Mount Battery

My battery is mounted right rear.I ran my + cable under the rear floor (fastback) and forward using the factory wire channel and covers to the inner firewall to an insulated pass through bulkhead post. In the engine bay ,from the post to the starter relay and post to starter. My fuel pump relay is in the rear mounted next to the battery. My interior fuse box is powered by a 100a maxi fuse from the interior side + post. Fan relays are on the fan. Ignition,horn and F.A.S.T. XFI relays are mounted behind the glove box fuse box. I also ran the - cable forward (after grounding the rear of the car) down the right side channel ,out the right kick panel antenna hole and forward to the frame rail(welded stud) and a stainless strap from the stud to the engine. The multiple ground locations reduce current draw and voltage drop.
