Hello,

I have a 2005 V6 Cayenne. I am installing a trailer hitch as the truck did not have one when I bought it.

My plan is to install the Curt aftermarket hitch and the Porsche factory wiring and controls.

I have purchased the Porsche factory parts as follows:

955-618-040-10 Control Unit
955-612-506-00 Wiring Harness
PNA-955-118-93 Trailer Hitch Connector (this is the 7 pin Pollak connector)
PNA 955-127-08 7-4 way Adapter

I am going to get the Curt hitch installed saturday at a hitch shop but plan to install the wiring/control unit.

I have done a search and reviewed the TSB (I could only find the TSB on the electric trailer hitch), but I'm wondering if anyone has some advice on the install process for the wiring and control unit.

Any help would be very much appreciated.

Brent

Hello Brent,

The control unit is a small plastic box and if I remember there is 2 or 3 plugs to attach on the module. If you look on the trunk on the passenger side in the compartment over the wheel you will find all the connectors pre-wired. All of them are wrapped with grey foam. At first view the curt kit may look to cost you less, but if you buy all parts piece by piece, it's cheaper to buy the original kit. I installed by myself in about an hour max and I'm not a top mechanical. You need only to remove the crossmember put the hitch and foampart and clip all the plugs. All of them have different size and shape and it's impossible to make a mistake. The only bad thing is the new cayenne model come with smaller size bolt to hold the hitch. I needed to buy specific bolt to hold it, this is steel structure bolt category. The price to buy 8 bolt at porsche dealer was the cost to buy a full box of 48 at a specialized bolt store. So if you need some I'll give you 8 at no charge, you just pay the shipping cost. (I have 40 left if this can help you) M14 100mm I had ordered a curt kit and resell it on ebay.... When you will see the difference side by side it's like day and night.

I strongly suggest to buy the P4 brake controller, it's like having nothing in tow and dont need any adjustement.

I'm pulling a 5,000 lbs trailer regulary with my v6 and the cayenne is a very good towing vehicule.

The TSB is attached, if you have any question, dont hesitate to ask,

Thanks,

GUY

So you removed the rear bumper covers, removed the existing bumper, cut the valance and mounted and wired the hitch assembly in an hour ? You did not have to take it to the dealer to programme ? What model year are you driving ?

It's really easy to remove the bumper about 10-15 mins and then 4 bolts for the cross over, all plugs are pre-wired to the towing control unit. To cut the valance I used aluminium scisor and if you look on the back side there is a line on the valence, follow the line and cut like a piece of paper. You just need to buy a part from porsche, the 7 pin receptacle to put on the circle with four small screw. Again this adaptor is prewired to the one running inside the factory hitch.

May be at max 1.5 hour to do everything. And if I change for another cayenne, I will redo again in one hour sharp. Keep your crossmember just in case. I have a 04 cayenne V6 see larger picture with our trailer, 11,000 pounds for both vehicule at the scale.

If you need any supprt or document, let me know.

I did this 4 years ago, I know exactly whats involved, see my gallery on rennlist. The Dealer had to program in the hitch, maybe because of my Air Suspension. Also not all Cayenne have all the wiring in place and fishing it through is a PIA

very nice, that's what I was looking for. I usually trailer the offroad bike, and some times maybe a boat or a small trailer.
could you please tell me which was the model that you've got? I mean, there are different dimensions and I dont know what to choose.
thanks,

Is the brake controller really necessary for towing boats and things that don't have trailer brakes? Or will the wiring not work properly without it. I only anticipate I will pull a Jetski and possibly a car trailer for short distances and will never need the controller. Any help would be great.

[mudman2]

If your trailer does not have brakes then you dont need a controller

For the wiring can one simply splice into the harness to power the trailer lights? Or do you need to do something special?

Hi Brent,
Just curious how the hitch installation went. I am looking to do the same thing and just looking for input on the project.
Do you have any pics of the completed install. What did u use to cut the fisca on the bumper. Also i have rear sensors on my 04 cayenne s, with they have to be reprogrammed ?

Thanks.

The rear sensors are not impacted by the install, my gallery on rennlist has pictures of the mechanics not the electrics tho

So after you installed the curt hitch you didnt have to re-configure sensors or any of the electronics. Doesnt it beep continously when you have tow trailer in place and are backing up.? I see you sjust spliced the wires , i want to add the 7pin to 4pin adapter for more cleaner connection, any input on that.?

I heard that the Tow hitch of a toureg is identical to the OEM cayenne hitch. It cost $200- $300 dollars less. Any input on this.?
