The Tech Bulletin that you were looking at, see link, is the best resource we have for installing a brake controller on the 2006 Volkswagen Touareg. I think that I can expand on the instructions a bit to make a bit of sense out of the wording, and I have a photo of the parts you should get, see link.

You will need to purchase 2 wire assemblies from VW, part number 000-979-228, that will have wire terminals on both ends. You will need to cut each assembly in half to create 4 wires. The 4 ends with terminals on them will plug into the connector you get from the dealer, part number 1J0-972-782, install one wire in each of the 4 numbered slots in the plastic connector.

Connect the white wire from the brake controller to the wire installed in the number 1 position in the connector. Connect the black wire from the brake controller to the wire installed in the number 2 position in the connector. Connect the blue wire from the brake controller to the wire installed in the number 4 position in the connector.

The red wire from the brake controller must be ran to a wiring relay like part # A-715, Connect the red wire from the brake controller to the # 87 terminal on the relay with a female spade connector. Next, connect the wire installed in the number 3 position in the plastic connector to the # 86 terminal on the relay. Finally connect the # 85 terminal on the relay to ground and the # 30 terminal to the positive post of the vehicle battery with an inline fuse holder, # 18167-1, installed inline. Install a 5 amp fuse in the fuse holder.
