Yes you can just run a neg cable between the two. It should be the same size cable as the positive. In many cases this is more reliable (& can also make any future fault finding simpler) than using chassis earth.Quote:

Thanks Cuppa. I don't see many people doing this most just ground it to chassis so I thought I better ask if there was a "negative" in running a hard negative between batteries as well as grounding it. I'll do both.Quote:

Took advantage of good weather today, and finished the dual battery system. Was hard finding a spot for the redarc unit so, i made a stand-off bracket, for it, and fitted the fused on top, works a treat and looks neat. Ran 2 twins to the rear, which I'm yet to terminate into a some form of fridge plug? I'm not sure what the ARB fridge plugs into until I buy one. And one of the circuits will be just tapped into a 6 way box and spread from there onward to lights and other gadgetry.

So I want to wire up my spare wheel bracket/light for 2 functions. A reverse light and camping/general rear light.
Whats the best way to go about it? Put a relay in, that's triggered by the reverse hot wire, and also have a switch that triggers also triggers the relay when I want the light on manually. Does this sound feasable?
Looking neat mate. As for the reverse light, that's how mine is setup. Comes on with reverse, but I can also turn the rear light on via a switch. Which also turns on the reverse lights to but it's no issue to me.
How it's done was via a relay but I can't remember how. MudRunnerTD showed me how ages ago in a thread here. I'll see if I can find it if you like bud.
A few option in here for your wiring re the reverse light http://www.nissanpatrol.com.au/forum...n-switch/page2
Hodge loved how you cable tied the spare fuse. Great idea!!!
Heres the thread that Daren helped me with. Starts from about post #19...

Thanks fellas. Have been going through those threads and some other reading ... It's amazing I work with power every day yet car electrical gives me a headache. lol
I was looking at Darrens drawing, and it is perfect for what I need... however. With that setup, when I manually turn on the light, the reverse lights will turn on too. This is something I want to avoid.
In a nutshell I need a relay that can be triggered from 2 different sources ( reverse light and manual switch), yet not interconnect those 2, if that makes sense ?
