Dual Battery cable location ...

Ooops - dropped a "w" up there --- LOL - its two lengths of hose .

Each to their own ,methinks however that trying to pass a thick enough wire through a garden hose the length of a vehicle is a exercise in frustration , much easier to buy convoluted tubing designed for the purpose.

Sounds like ya did just fine.

I would have some sort of fuse/circiut breaker at BOTH ends of the cable in the unlikely event it does decide to short out.

Steve the important thing with any electrical installation under the car is avoiding pinch spots,(remember the body moves on the chassis) the heat off the exhaust, area's that could catch a stick & avoid tieing to brake or fuel lines. Water (& dust) is not normally an issue as long as the wires pass through the body in sealed grommets.
I have just run wires to the rear of my JK but have routed them inide the car to avoid the cables being caught or squashed. I used 35mm cu with the positive in corrugated conduit passing through the firewall then along the passenger side floor kick panels, inside gaurd then out through rubber grommets & into the battery box. A pair of fused 12mm cables then runs to an Anderson Plug at rear of car again in the split conduit.

I always run my cables through the chassis. Not difficult. Just get one of the yellow 'tongues' that come in chipboard flooring sheets. They are stiff enough to be able to push through, but flexible enough to get around bends. Tape the cable to the end of the tongue and pull it through.

I use the split flexible tubing over the cable where it enters and exits the chassis, otherwise, the cables are just resting inside the chassis.

I have now done this on two vehicles and I believe the effort is worth while to ensure the cables can never be snagged on a branch or rock when off roading.

Steve, if you use the garden hose idea (should be good if you can get it right out of the way), I'd have thought it would be easier to get the cable through the hose before connecting it to the vehicle. Split tubing would be much easier to use though as you don't need to thread the cable through.

Put some of the soap you use for the dishes in your hose.
This makes it all a bit easier when you try to pull the cables through the hose.
I don't know how big your cables are, but if you have some space left, pull a small rope in together with your cables.
It sucks the moist that might enter, out of the hose.
Do leave a centimeter of 5 hanging outside the end.
