Some of the worst pictures I have ever taken - but I was in a hurry and promised a few of you some pictures showing my install on a 2010 "T-Rex & "Egg"

When I get a chance in the next 30 days I'll mark the pictures up to clear a few things and post as a new install cheat sheet...

BTW - it was five years ago today I posted my Cayenne S Brake Controller Install - Wow...

2010 Touareg TDI Brake Controller Harness Install

■ Here we are with a quick picture just showing everything "as from Germany" before we take out the panel to access our harness - note the diagnostic port on the left and the lower wheel well light on the right.

■ Violating the poor girl by removing her lower valance - note the diagnostic port blurred in the foreground - see any brake controller OEM harness? I sure don't as it isn't in the same place as was the last time I did this five years ago...

■ OH - here it is - way up in the top left and hidden behind that other big OEM bundle - I had to really search for it (thus why I'm sure folks are claiming they stopped installing the Brake Controller harnesses) - actually had to feel around for it - that is how well hidden it was! Here it is pulled for a photo op...

■ Now a picture of my harness completed and ready for install - note the switch for powering both the Prodigy & Relay with the 5 amp fuse inline (its the 12 volts goofy) and the Volkswagen\Audi\Porsche connector ready to plug into that OEM Brake Controller Harness that we just found. Oh - and YES I know I like the purple tie strips (didn't really need them as the cold fusion tape works great - but those strips are in strategic locations to reduce stress as well as keep the wrap on - just in case)...

■ So now I have connected our harness to the OEM Brake Controller (female with matching male) harness. You can also see where I placed the relay and now I just need to connect the switch to the lower valance panel.

■ Here is a nice picture after I mounted the toggle switch to the valance for the 12 volt power for the relay and Prodigy - you can see the relay sitting in its perch (with some blue loctite visible as well) and I'm now getting ready to place the Prodigy harness through the diagnostic port opening before I snap that back into place - don't forget your little wheel well light over in the right corner!

■ Everything back together now - just need to mount the Prodigy and then plug it into its harness sticking out as seen and we can start towing. So glad I put the switch in the circuit as suggested by my fellow "bros" to disable the relay and power to the Prodigy (The Prodigy goes to sleep on its own when not used - I don't think the relay needs to always be energized when not in use - so I remove the power to both devices when not towing...

And what good would I be if I didn't post final pics of the P3 as installed....

And for the person who asked for a picture with the brake pedal being used to trigger the trailer brakes (don't ask me why they asked) here is your pic...

Very similar to how mine ended up on the BMW X5.

Great write-up. Someone like you who takes the time to do a job well and document it for others to follow their example are truly appreciated.

I put the photos in lytebox explained here:

I PROMISE for now on to use the lytebox - (which is new to me but very, very cool)!!!

Glad I could submit - thought I better show some value before I go reading all the great knowledge others have already posted on the Forum...

Thanks again!!!

No worries.

Glad to have you...Lytebox or not.

[but using Lytebox sure helps out]

Quick change to my instructions - swap out the 5 amp inline fuse with a 30 amp inline fuse - that's if you even use the inline fuse....

Otherwise this works GREAT!!!
