Trailer plug adaptor

[Kev. ug]

Hi I'm new to the forum and grateful for any advise.
I have a Trialmaster in Australia with the 13 pin round plug as supplied. I'm toeing a 2-yr old caravan, I also have normal red and gray Anderson plugs.
Can anyone recommend a 13-pin round to 12 pin flat adaptor that won't bring up trailer warning light on the dash every time its plugged in? I believe there needs to be diodes or something within the adaptor to stop the warning light coming on.
Regards
Kevin

There is a thread somewhere. I will try and find it. I will also look in the Rok Dr Guide.

Your homework, look here:

Look at para 11.1 of the Rok Dr Guide. Options are set out.

You can get the 13 pin Euro plug converted to an Australian style 7/12 pin, see XHQ options in Point 5 of next post. I had this done and it works really well. I also got the needed Anderson plug and REDARC Tow Pro at the same time.

Also worth printing out a copy of the Rok Dr Guide and keeping it in the car.

TOWING GEAR - AU

1. Allin Towbar, send an email, it is a custom order. Look here. I own one, very impressive engineering! Capacity 3.5 metric tonnes, 350kg max towball weight;
2. Allin also make a variable height towing mount, a custom order;
3. Hayman Reese, look here;
4. A Gen-Y Hitch can also work, look here; and
5. XHQ Towing Kits converting the IG’s 13 pin Euro plug to an Australian style flat 7/12 pin plug. Look at packages 2 and 3. Package 3 is not offered for the 2 seater Utility Wagon (it seems my 2 seater was the only one every installed). XHQ use their own wiring loom in their kit. XHQ have verbally confirmed to me the 12 pin flat plug has all the 12 pins wired, not just the standard 7 pins (confirmed by phone on 9 Oct 2024).

Thread 'AUSTRALIA: Third Party Suppliers for the INEOS Grenadier and QM'

Jan 3, 2024

PART 1
The Quartermaster's chassis is longer than the Grenadier's, so not all the Grenadier's accessories will fit (like the side steps and rock sliders). QM owners should double check accessories fitment.

AIRBAG SUSPENSION (see also SUSPENSION HERE)

1. Airbag Man suspension for the Grenadier and QM, both come in standard and 2 inch lift kits. QM kits here and Grenadier Kits here;
2. Heasmans (Sydenham Sydney) can can do Polyair airbags and Bilstein suspension;
3. GrenX Polyair Grenadier Ultimate Airbag Suspension...
