I started to work on moving my battery from under the hood to the truck so I have the room for my remote oil filter relocate. I made some good progress today. I began by selecting the location for mounting the battery in the right rear corner. I marked the holes to drill and jacked the back up so I could remove the heat shield from above the muffler. The bolts would be above it so I needed the access to be able to tighten them down. Here are some pics of the holes from underneath the car. I painted the holes that I drilled out to prevent any rust issues. You can see how I had to place it just right to get the bolts in a position that I could get to them! I bought a battery mount specially for the Optima battery and using this I don't need to use a battery box. Here you can see the positive 0 gauge wire that I ran from the engine compartment through the car to the trunk. A test fit and it looks great! You can see how the battery is held down with this slick hold down. I tried the carpet so it fits perfectly around the battery like it was meant to be there! Before reinstalling the muffler heat shield I sprayed some undercoating over the bolts and nuts. All ready to make the connections now!
