Thread: Power to the rear D4

Are you referring to the white tow-plug on the back of the car?

If so, Pin 6 provides ignition-switched 12V power, with corresponding earth on Pin 7. There is also a permanent 12V on Pin 4 - and note there is a separate earth for this on Pin 3.

AFAIK, neither are speed dependent.

Cheers,

Gordon

Hi gghaggis, interested to hear about the permanent power on pin 4 of the white plug. Has anyone found its source and tapped into it for permanent internal rear power? I realise its not ideal as its off the cranking battery, but if used wisely it could be a neat easy way to get power 24/7 to a rear intenal power outlet.

Thanks Gordon, and yes the white plug.

Hi Roger,

It's a 20amp fused supply from the cranking battery. I think the wiring runs behind the rear passenger quarter panel, but access is different for different models (D3, D4 or RRS).

I found the two wires in the back left panel. They both go into a white click on cable joiner (the two cables are by themselves). Just use a test light to determine which is ignition and which is permanent....or look at the back of the white trailer fitting. The ignition on was the lower cable of my D4.

So cool having much of the pre wiring done for you.

Is 20 amps enough?

Hi Stuart, and it depends on what you want to use it for.

If you want to power some camp lights or run a compressor type fridge, not a problem. You could even run a small inverter but no bigger than about a 150w.

The 20 amps is not the limitation, it’s the thickness, or more correctly, the thinness of the cable that is the problem is the cable is too thin for anything that requires both decent voltage and current as this size cable will cause a fair bit of voltage drop with even a moderate current load.

It’s no where big enough to run a decent size 3 way fridge off and don’t think about charging even a small battery, you will spend more time replacing fuses then actually getting a battery charged.

The dreaded voltage drop...
