Trailer pre-wiring AUS Delivered Tiguan

[kroogz]

Hi There,

Just wondering if anyone could help me.

Can someone confirm if Australian delivered Tigs come with trailer pre-wiring.

I took my boot lining out yesterday and found the RED plug that goes into the trailer module but no BLACK plug that goes to the socket at the hitch.

Any ideas?

Cheers

Yes they are pre wired since about 2010. You have the red plug that will go into the control unit for the trailer, then in the kit you buy that has the control unit you also get the wiring to the tow ball which is the black plug also to the other side of the control unit. Then you just need to join the CAN BUS wires under the dash on the drivers side and then code to the gateway and your up and running....VDUB...

Thanks for the feedback. I thought that may be the case, but some of the DIY's make out as if the black cable should be on the car already.

[vdubmotorworx]

No.. just the red....VDUB...

Are you buying a VW kit ?

[kroogz]

I was looking at this kit and been talking to the supplier. 2009 2014 VW Volkswagen Tiguan Complete Trailer Hitch KIT Genuine Brand NEW | eBay

Are you able to source this kit?

They're not ADR-approved.

There's an Australian-specific towbar for them, but the wiring kit is the same.

[kroogz]

Ah no probs - do you know the code for ADR approved version? Is it DIY friendly?

[vdubmotorworx]

Have you priced it up from vw parts? Not all stuff is more expensive....ie. repco vw brake pads are more expensive than gen vw from a vw parts guy!...VDUB...

[kroogz]

I did actually ask VW parts at local dealer and they couldnt find the part

[kroogz]

I do want to buy the VW OEM electronics kits, but I was worried it did not come with the harness that goes to the socket. I will have to try and source an ADR towbar.

Do I remove the current cross bar that has the OEM mount points and replace with the ADR compliant?

[Umai Naa!!]

Yeah, throw the one away that's on there.

It's not very substantial. I wouldn't hang a bike carrier off it.

They're not too bad from a DIY sense. You have to strip a fair bit off the rear of the car, though. The CAN wiring up under the dash is a pain in the backside as well.

[kroogz]

When you say pain in the back side, are you refering the Y peice that needs to be installed near the OBD port?

Not a Tiguan - but i am currently removing a genuine VW (made by BestBar) towbar from a 2010 VW Golf. Im sure it's similar to the Tiguan.

The towbar replaces your OEM rear crash beam - so your OEM crash beam is no longer used.

As for the wiring, there are 2 parts:

- a wiring loom thats approx 1.2m in length with a black plug (this is the part that plugs into a module on the passenger side and runs down to the towbar to power the lights on the trailer)
- a wiring loom thats approx 4m in length with a red plug (and separate earth lead) at one end, and about 8 or so wires at the other end. The end with the red plug and earth plugs into the module in the passenger boot (unclip OEM red plug and plug in aftermarket red plug). The other end runs up to the drivers side dash. 3 red wires and a blue wire go into the fuse panel (and replace existing pins in this fuse panel) and the remainder of the wires go into the CECM (central electronics control module) which is also under the dash.

Thanks Lucas.

I think my Tiguan already has the RED plug pre-wired as I took all the passenger side panel out last night and it was sitting there.

I did not find the BLACK plug though, so I hope the VW OEM electronics kit comes with that loom.
