Hi,

I've got 2004 4.4 v8 petrol, and I've installed a second battery in the rear and am wondering which fuse is ignition controlled??

I've plugged the kit (from Luxury Land Rover Upgrades) into the cigar socket fuse (No 71 / Slot 1) in the rear but suddenly wondered if it's ignition controlled (like my Audi) or whether it's constant live?

Thanks for any help

The sockets are permanently live, until the 2010 facelift, then they are not.....ask me how I know 🤣 ask me if I spent best part of £300 on a cool box I can’t really use. 🤣

I know I could bridge something.....

So you should be fine.

As above none of the fuses are ignition controlled but running above the fuse board is a thin green wire which is ignition controlled. Depending on what you want to achieve this wire can be used to trigger a relay, the output of which is then ignition controlled.

I should have said that I’m after an ignition controlled fuse so that I can plug in to a relay, so that the battery isolated when the car isn’t in use.

I think I heard that someone has used the fuel pump fuse, but not 100% sure, Andy if they did if it was right to do so or not.

Cheers

I’ll take a look for that green wire tomorrow 👍

The green wire is actually green / yellow ( ) and is in this harness, just find a convenient place to splice into it.

The simplest and in my opinion the best way to connect a 2nd battery in the rear is by using a cheap voltage sensing relay. Take the live from the big red cable going to the rear fusebox. I would also recommend lifting the loom out of the void to stop any chance of the battery rubbing through any wires. Simple and cheap

Hi Oggy,

They said to use the fifth fuse along but that's for the rear blower, so they must have been using a latter RR and they haven't gotten back to me when I've emailed them.

Their kit is pretty good and does link to the big red cable at the rear fusebox. It has a relay and the negative goes to the body (after clearing away the paint). I did move the loom off of the floor and moved it to the front of the battery so it won't rub. I also used my Dremmel and removed the captive screws the cable ties were on, which means the battery sits nicely on the floor and all the trim panels go back with no problem.

Here's a picture of the kit (from someone elses youtube channel)

The VSR in my link goes between the 2nd battery and the fuse box main feed red wire, similar to your pic. When the car is running the 2nd battery gets charged, when you turn off the engine the 2nd battery is isolated. Fully automatic, no chance of forgetting. The beauty of this is that the charging must be over 13.8v before the switch, not 12v or less with a standard relay. Don't forget a meaty resettable fuse, I can't see one in that pic. I have connected my rear 12v socket directly to the 2nd battery having removed it from the loom 2007 TDV8 VSE

So an update on this. I've had Luxury Land Rover Upgrades contact me and they've said that I can splice into the Green cable that goes into the towing connector (white block near the fuse panel on the rear). So I'm assuming that's the same Green cable that was mentioned before.

He's going to send me another cable that will replace the fused cable so I don't need to go to the fuse panel.

For info his website has a few decent bits of kit and he's also said that he's going to be selling plug and play Bluetooth kits for these older RR soon.

Cheers for all the suggestions everyone

hi batfink that is sounding a lot better yes i would say that is the one that niceday is talking about does this wire fire up the relay will that still be fused or not new vehicle purchase

Apparently there’s no need to add a fuse as he said it’s fused upstream from there already.
