Pretty much but I usually buy them with the fused battery post and the ground cable.

I run it up and under the back seat and then inside the passenger wiring gutter. I add extra conduit on the cable for protection. I don’t fuse it or use Ford solenoids, just like the OEMs…. :)

Do you use a thru-firewall setup like these or do you pass the positive wire thru a grommeted opening? Techflex covering or something heavier?

I use the thru bulkhead like the one on the left. Just techflex, one or two layers. The insulation on that OEM cable is quite thick.

Im guessing Patrick has some advice to offer here… :)

Placing the battery in the trunk provides better weight distribution on the car. The battery should be placed in the center of the trunk directly over the rear axle. This will help the car handle better. My car is a convertible. It is not feasible to mount the battery in this location. The second best place is the passenger side area in the trunk.

I ran a 1/0 cable in conduit. 1/0 cable was selected because it will have slightly less voltage drop compared to the shorter stock cable used with a front mounted battery. I used flex conduit over the wheel house and PVC conduit along the passenger rocker. The red line shows the path in the photo below.

The conduit is 1/2" diameter. 3/4" conduit will not fit in the rocker. Make sure the outside diameter of the cable you select will fit inside the conduit hole. What people call 1/0 welding cable will not fit in a 1/2" conduit. I used an industrial type THWN-2 cable that is oil, gas, sunlight resistant. It has a 90 degree Centigrade temperature rating. It is not a fine strand cable so it is stiff. I was able to pull the cable into the conduit by hand. At the other end of the cable there is a mounting insulator on the firewall. The mounting insulator is similar to the ones mentioned in the above posts. A second cable goes from the mounting insulator to the starter. The type of cable will be a SGX cable. 1/0 SGX cable will not fit in a 1/2" conduit but it is flexible. It is specifically designed for use in automotive applications. Notice I used two different types of cable. I used a cable that matches the particular conditions the cable is applied. The photo below shows the start of the cable pull.

The wire covers and plastic kick panel still fits. No extra holes were drilled except for the hole through the firewall. The quarter panel window still goes up and down.

This is my rear battery and accessories fully wired. The temporary battery will be replaced with a 78 style battery. A 78 battery will fit in this tight area.

The key disconnect switch provided a post to wire several cables at one point.
