Hi,
I'm about to install wiring from my dual batter to the rear of my Gen 3 SWB Pajero. I'm thinking of runiing 16mm2 cables to the back. The std 12V cigarette outlet is on the passeger side - I think I'll leave the std socket as is.
I'll be running my fridge and some lights and a small inverter... but with 16mm2 wire, I should be able to run my compressor (40 amps) from the rear as well. I'd use a Anderson (Brad Harrison) socket.
Does anyone have a photo of how they mounted their Anderson (Brad Harrison) connector in the rear of a Pajero? I thought I could make it come out at the back seats, and just let it rest on the carpet (in the boot area)... or I could maybe mount it on to the plastic tim at the back? Are these connectors difficult to plug in and out? Will the plastic be strong enough?
I will then make a small distribution box that connects to the Anderson plug, and has 3 x Hella sockets, that I will use to commect the fridge, lights, etc. The distribution box could also have another Anderson socket for the compressor.
Anyone done anything like this?
Cheers
Greg
Is this the one?
I saw one fitted to the plate of the towbar's plug today. Seems quite a logical spot, and simple to get the wiring there along the towbar's cluster. You can feed wiring in to the rear from there.
If you need it on the inside, I suggest you bring it through (under the paneling) to the rear utility plug.

Mounting it on the towing cluster does tend to expose it to the elements and corrosion. On my baby I pulled two circuits to the back. One wired in 6mm cable and protected by a 25A fuse that feeds two normal cig lighter plugs and one 10mm on a 45A fuse that supplies two hella plugs. In the case of a short the fuse pops right next to the battery and the risk of fire is prevented. The fuses are normal blade fuses and the holders came from the local autozone as did the plugs, cable was scrounged from trailing cable that I had lying in the scrap box

Good point. It is better on the inside when the purpose is to use it inside. Fit it to the side-panel, and don't let it lie on the floor - there it is likely to get caught and pinched, which may lead to a short or damage of your plug.HBannink wrote:Mounting it on the towing cluster does tend to expose it to the elements and corrosion.

The wire quality is most important. Have it as thick as possible to prevent overheating and reduce fire risk.
That monument of a burnt-out Jeep in the Caprivi is due to a fire caused by too thin wiring to the rear...

- The 16 sq mm wire thickness is to counter act the voltage drop whilst charging, IF THE AUX. BATTERY IS AT THE BACK. If you have the aux battery in the engine bay, you need wires only thick enough to power your equipment. (someone will be able to suggest the required thickness, if you supply the total Amp draw for all the equipment)
- Running the equipment you mention will require thinner cables / wires.
- the BH plug has a hole through which you can fit a screw / bolt to fit it to any flat surface.
- I would install comprehensive fuses:
- a ±25A fuse in the engine bay (where your 16 sq mm start)
- an appropriate fuse on each of the the plugs of your 'distribution box'
- the orange plug in tonton's post has a Amp rating much higher than what you need (I think 100A). You need the grey plugs

Thanks for all the replies 
I was mainly concerned about mounting the Brad-Harrison plug, and if anyone else had done this. so it looks like I can mount it to the platic in the rear - or I'll make a bracket, or something.
As mentioned, I will have the battery under the bonnet. If I run a compressor from the rear, the 40A current will require a decent size cable to prevent a large voltage drop. The 16mm2 will give a voltage drop of 0.8V (for 8m) which I am happy with. This will be fused at the battery.
I will add fuses in the distribution box (one per hella socket).

I thought the idea with the DC-DC chargers is to be installed close to the battery being charged? The advantage of the DC-DC charger (besides the 3 or 4 stage caharging), is that they had handle a lower input voltage (as low as 10V), so you can have a thinner cable between the main battery / alternator and the DC-DC charger (as the voltage drop doesn't matter so much). Or am understanfing it wrong?4ePajero wrote: PS. If I have to do it again, I would not run the thick wires to the back. I would install a 12v DC-DC charger in the engine bay, with thinner, fused wires running to the back (thick enough to run your equipment).

That is exactly the advantage of the DC-DC charger. You can install it anywhere, with thin wires (thick enough for the max. A rating of the DC-DC charger) and as long as you have 10+ Volt as input, it will charge the battery (intelligently).Greg_SA wrote: I thought the idea with the DC-DC chargers is to be installed close to the battery being charged?

Running cabling from the battery (regardless of how it is charged) is another subject, which I think is what you are talking about in your original post.

Just wondering if anyone has removed the rear power socket in a Gen 3? I can't figure out how to remove it - was thinking of replacing it with a Hella socket.

Apparently you have to remove the trim first.Greg_SA wrote:Just wondering if anyone has removed the rear power socket in a Gen 3? I can't figure out how to remove it - was thinking of replacing it with a Hella socket.
Why don't you rather leave the socket there and add new wiring for a Hella plug in addition?
