Dual Bty wirinig for Prado120 V6

Hi Drew,

Swapping the batteries use (crank to Aux) is probably more trouble than it's worth. The Pirahna tray for the 120 series will allow you to fit a full size battery. It comes with the bracket to relocate the power steering fluid reservoir. It's all pretty basic to install, I took my time, and probably had it done in 1.5hrs.
The battery I use is the Exide Extreme.
The Redarc isolator is mounted just behind the engine bay fuse/relay box. I also installed an eight way fuse block on the firewall, where I distribute my aux power.
I've run a new heavy duty circuit to the back, with a Hella socket for the fridge. I've also patched into the factory power outlets (front console & back) by removing the factory fuse and running a new fused circuit from my aux fuse block to the positive pin of the console power outlet. This circuit is only for lighting, so voltage drop is not an issue.
Regards,
Tony

Hi Drew,

I've been away, so haven't had a chance to catch up on the e-mails.

It's pretty easy to run the cable to the back.

I ran both +ve and -ve in heavy duty cable for the fridge outlet.
In the engine bay on the passenger side, there's a rubber boot (about 70mm diam) with a couple of rubber knobs. Cut one of the knobs off, and the cable will go through there. You'll probably need to push a solid draw wire through first, since there's a second rubber part on the inside.

Inside the car, remove the trim along the door sills (passenger side), the panel under the glove box and the kick panel. The cable will come out on the firewall behind the cars CPU. No need to remove equipment, just hook the draw wire out into foot well. Connect the cables to the draw wire and pull it through the rubber boot. Be carfull not to pull the boot away from the firewall. The floor channels are easily big enough for the extra cables.

Inside the rear of the car, I removed the tray in the side panel above the passenger side rear wheel. I was then able to push a solid draw wire down inside the rear wall lining to the passenger side rear door sill.

The outlet was installed just above the tray hight in the little alcove above the passenger side rear wheel.

Take your time and think about what you're dooing and you shouldn't have any problem.

Regards,
Tony
