Might as well post pictures of my battery relocation just for future reference for anybody who is interested. I used 4 gauge power wire to go from under the hood back to the trunk. I ran mine the same way as presure2 did, under the carpet on the driver's side of the car, behind the plastic in the back seat, and then I ran the wire between the rear seat and up through the carpet there and into my custom built box. Presure2 and Batman chose to ground to a U shaped bracket that the rear seat latches to, whereas I chose to ground mine to the bracket that the rear seats bolt to in the center of the car. I will edit this post with pics of that as soon as I get my real camera going again. For the box, I built it myself using materials I already had sitting around. It's simply a piece of plywood and some black denim. I could have bought a plastic box that would serve the same purpose, but I chose to save my money and build my own.

Although this battery relocation is currently fully functional and cost me less than $50, I will be adding some things to clean it up later, and I will post more pictures when I do. I will buy a junction box to go under the hood like presure2 used, as well as a grommet to run the power wire through my firewall. This will happen when I swap though, so that I've got an empty engine bay to work with.

TeamFaint: for some reason you don't have ABS, most Celicas after 95 including my GT4 do have ABS, which sits in that location you point out.

Even if you don't have it, that location doesn't look very practical.

As for grounding, I ground to boot & to the stock engine ground.

Used to have starting troubles with just a boot ground after alarm install.

thought i would share this, if you want to do this for a cheaper price you can use the cable for welders, works just as well and is way cheaper

I believe I remember a member who located it inside the center console (of course a small light weight battery that is)

can anyone recall

TEAMFaint> You mean something like this?


I'm using a caterham banner battery which is tiny and light weight.
Made my own battery tray out of aluminium.
My build was always about balancing weight and trying to keep it performing like or better than stock.
This is actually an old pic. Since my battery is properly strapped down and my intake has changed and I saved more weight removing the original battery tray by drilling out the welding points.

What I found with many DIY relocations in the boot is that many people suffered weak start up and poor earthing.
Doesn't matter if you earth 5-10 points in the boot you should really earth it close to the front, to the alternator and even onto the engine.
DO NOT USE JUMP CABLES! Unless you want it burning up as I have personally experienced when the cables melted and end burnt off.

IF you want it in the boot, go to the salvage yard and find a BMW. They tend to have the batteries in the boot so salvage the cabling from them and wire it in the same way. Cheap and effective.

this is how my battery terminal turnd out after the connection kept on sparking cause of wear and tear. i feel like this is not a solid connection what do i do??

Sand and file it clean.

Put it all back together. Get a torch, heat the area. Spin up a bunch of solder, and make sure its heated realllly hot, and the solder will just melt into the joint.

Or, just tin the shiz out of the wire.
