Trailer Wiring

Hi,

So the plugs behind the cover on the d3 for trailer electrical connection ...

Question 1: Why is there 2 ? Which one do I use ?
Question 2: Is it a standard connector ? My trailer has round, not flat like my d2 did.

Bye,
Scott

Scott - the black 7 pin is the one to use. The white one is LR specific and if you had the right coupling, the air suspension would only stay at Normal height - you could not change to Access or Off Road Modes (connecting to it enables that Normal mode only). BTW - it does have a name but I can't remember it; maybe someone from the Wet Isles will be along shortly to remind us all of its name...

If you don't have a large 7 pin plug on the trailer, you could try for an adaptor at SuperCheap, Repco, etc. or have an auto electrician make one up for you.

HTH, Leigh

the black is 12n while the white is 12s and I believe the suspensions auto feature is disabled but can be manually changed.

So what are u saying Scott, "which one do "I" use...

As said black for Aus, White for USA.
Wiring can be changed as i said previously to give permanent power to the plug if u need to know let me know.

Cheers

Yep, stops it automatically lowering and raising but you can still do it manually

12S socket is mainly used in the UK for caravans, pin out is in the site somewhere if you want to make use of it (assuming you can get the plugs over there, if not I'm sure we could send one over)

Thanks Slimer, I didnt know the UK used the "White" plug, i had thought it was mainly for US. Shocked
Our vehicles are pre-wired & have both plugs fitted as standard, even on base vehicles.
We have a lot of customers asking which one do i use... Surprised

do a search for 12s, some in Oz do use it for fridges and caravans and the plugs cost about $20 or so including post from the UK

Yes, just signed today on a second hand HSE. We get it tomorrow. A very BIG thank you to everyone for their advice.

So if I use the black one, will it take the standard 7-pin round plug from my trailer, or is a "different" connector ?

Bye,
Scott

Ummmm, If the 12s white plug is used and it stops suspension auto lowering Idea could the suspension be put in off road hight and stay there above 40 km/hr. If so a plug could be fitted with some load equal to lights and the thing would think a trailer was on and we would have controle of the suspension. could this be possible Question

Rob Bow down Bow down This would seem too simple to be true , oh well Bow down Bow down

Rob,
Err, if you are successful you might let on? (There might be a good business in white plugs fitted with little LED lights!).
