Routing the relocating battery cable
 
From the engine bay fuse -- where did you route the positive cable to reach the trunk area?

thank you

Thru the driver side fender. Below the cruise control module there is a hole. You need to remove the fender liner. Once inside the the cabin then route the cable underneath the carper along the door sill all the way to the back.

thanks VR
how about the negative ground cable....the best place to bolt?
Chassis ? body ? or there's a good area to bolt the neg cable to get a better ground?

if youre putting the battery in the trunk then find a large bolt somewhere and use that as the ground. i would suggest you tuck the stock ground away somewhere instead of getting rid of it.

get some 4 gauge wire, a nice battery terminal and something to attach to the wire to mount it to a bolt somewhere.

I also highly recommend an additional ground from the negative terminal to the transmission or engine. You can also link it to the original body mount.

4 gauge will do fine. 2 is a little better. You can get high flex cable that is easy to worth with at McMaster Carr.

I looked around at the spare tire area, there's a couple of bolts but they are very small 6mm. I don't know where you guys are connecting the ground.

Also, if I add another ground, can i connect to the original distribution ground cable?

Could you just run the positive to the starter instead the fuze box(thought read that somewhere on here.

Look by the yellow stickers, use that one. Grind the paint off

You sure can. Linking body, then drive-train will work fine. Of course, ensure your standard engine bay grounding straps are in place. You would be surprised what type of voltage drops you see without proper grounding.

Good advice here.

Running a separate cable from the battery positive directly to the starter is desired. The starter is hands down the largest amp pulling device on your car. Direct connection is very much desired. You can not run a fuse inline. Pretty much EVERY car manufacturer does this. Direct connection for the starter, and everything else runs through a main fuse.

From there, a 2nd lead from battery positive to the fuse box will work fine. Alternator can be linked to the fuse box as well.

ok, so no matter what need a pos to the fuze boxs? so could run pos from batt to starter then one from starter to box?

^^ Yes. In fact, you can just land the new battery cable on the starter stud and back feed the existing cable [from the starter] to the fuse box. Works great.
