trailer plug-in
I am installing the brake controller and noticed the receptacle that the trailer plugs into is not there on the 2011 cs. Is this a Porsche part or a common plug available at the trailer store?

It is for a 2011 CS.. My prospective trailer guy (who has done Cayenne's) said only surge brakes for an open trailer as the electric brakes - even with the Prodigy - type brake controller can cause a non "handshake" / proper communication between the trailer electronics specifically with the Cayenne's electronics.
What have been your, or other owners Cayenne experiences using electric brakes with a Cayenne? Thank you.

Now Cayennes and LED trailer lights are a whole different story.... (but there's a fix for that too).

Did lots of searches on here when I got my '06 Pepper. After a few wrong way /dead ends I found the best place to get the receptacle from JC Whitney, IIRC cost me less than $15 inc S&H.

Not exactly. A good old fashioned analog brake controller will work fine. Issues with Prodigy (and their variants) with regards to diagnostic pulses have been around since the alpha/beta years.
You can also get a "!" with surge brakes (since the brakes aren't there).
I've also heard you can get a "!" with LED lighting ... but I'm sure that is just an internet rumor.
No problems lately, why do you ask?

Lewis,
I have an '11 on order with tow package, air suspension, and PASM, I plan to order a new Trailex CT8045 soon. I agree that electric brakes are the way to go (at least for me), but Trailex is telling me there is a compatibility issue between older and new Cayenne's with electric brakes. They apparently hear complaints regularly from Cayenne owners with the handshake between Cayenne electrical and their trailers. This is unrelated to LED's, but more with the braking communications.
I plan to also check with some Porsche techs soon and see what they experienced.

For $22 I would go that route too. For some reason when I needed mine it was either not available or priced about $45 (don't remember which). VW dealer should also have it w/out the Porsche premium.

To wire the controller inside the cabin, is there a factory harness already installed there that you just tap into? If so, where would I look for it? (I do have the factory tow package installed on a 2004 S)

I would recommend you do a search on "brake controller" and maybe add "prodgy (sp?)" as there has been a great deal of discussion on this already.

Following is a installation document if purchased an in dash brake control unit.
The manufacturer apparently does not have instructions for newer Cayenne's, yet, but after speaking with them, for me, it seems the Prodigy RF is the way to go.
Installing Electric Brake Controls

Vehicles: 2005-2008 Volkswagen Touareg2005-2008 Porsche Cayenne
Issue: Installing a brake control on a 2005-2008 Volkswagen Touareg or Porsche Cayenne
When installing a brake control on a 2005-2008 Volkswagen Touareg or Porsche Cayenne, using the factory brake control connector under the dash, you will need to obtain the connector housing and wire/terminal assembly in order to assemble the brake control harness. The following parts can be purchased from a Volkswagen dealer.
Connector Housing #1J0-972-782
Quantity required (1)
Wire/terminal assembly #000-979-228
Quantity required (2)
The 2 wire/terminal assemblies will have to be cut in half to produce 4 wire assemblies. The cavities on the connector housing are numbered and the harness can be assembled as shown on page 2.

To locate the connector under the dash, you first have to remove the lower appearance panel. This will require removing (2) Torxhead screws. (See Fig. 1) The brake control connector will be to the left of the opening and wrapped in Gray foam. (See Fig. 2)
Note: If installing a Prodigy® or P3®, you may experience an erratic display on the brake control. To avoid or correct this issue, do not connect the Red wire from the brake control to the connector above. Instead, see page 3 for instructions on obtaining a brake light signal.

When installing a Prodigy®or P3®, you will need to obtain locally, a 12 volt normally open relay. Wire the relay as follows. See diagram below
1.Connect the ground terminal (85) of the relay to a know good ground under the dash.
2.Connect the trigger terminal (86) of the relay to pin #3 of the brake control connector.
3.Connect the red wire from the brake control to the load terminal (87) of the relay.
4.Connect the source voltage terminal (30) to a 12 volt source, this wire should have a 5 amp fuse installed in-line.
WARNING
Complete the installation per the electric brake control manufacturer’s instructions and mount the unit as directed. Perform test procedures as indicated.
