Calling on Touareg experts; does anyone know where I can tap into CAN high & low around the drivers or passenger seat? This is for a 7P, T3/T4

Hi,
The Touareg features several CAN networks. Depending on what you want to connect, you would have to tap onto one or another.

What are you trying to install, and which network do you want?

Hi, Thanks I realise. And in my simple understanding of Can network I am looking for Can high and low- otherwise coming from Can gateway(located under dashboard) pins 21 & 5.
Any chance this is available under drivers seat?

Hello chewblekka,
Its the Can gateway high and low.
Trying to install a sound actuator- same as what comes in audi sq7.
The actuator module needs to connect to Can gateway, so then i can enable it via vcds and get it to drive the actuator.

The CAN bus has several different networks: powertrain, comfort 1 and 2, convenience, infotainment, display, etc.

The sound actuator connects to the powertrain network, pin 5 orange/brown (CAN low), ping 21 orange/black (CAN high) at the CAN gateway J533. You can easily identify any CAN network as the two wires (orange brown and orange(colour) ), they will be a twisted pair.

You can find the powertrain CAN bus wires at the transmission control module under the right front seat. Pin 46 CAN High, pin 34 CAN low. When splicing your connections, you MUST take care. do NOT use crimp connectors. Carefully remove some of the sheathing on the existing CAN wires, strip about 1/2" off the end of the sound actuator wires and wrap them tightly around the respective wires. Solder and heat shrink. You do not want any noise on the CAN network, it will effect how it works.

Gold! How good is this information. You are the top expert, thanks chewblekka!
Yeah I saw the installation documents and it showed how to splice and connect to Can wires, now i know why.
This will save me from routing the wires all the way into dash and the work associated to pry open plastics and put them back- would like to keep it all original.
The tcm under the seat, how best to identify it from other black boxes?

It's pretty obvious which module it is. Says "Aisin" and "Getrieb" on the sticker, and the PN starts "0C8".

Singh do you ever get this completed?

Would love to hear some sound clips <img src="http://www.clubtouareg.com/forums/images/smilies/icon_smile.gif" border="0" alt="" title="Smile" class="inlineimg" />
Havent been home in six weeks so didnt get a chance, darn i have my priorities wrong:)
Hopefully it will be installed and working by the weekend. Will share sound clips then for sure.
Doing all the research to make it as much of a factory install meanwhile:)

Hi Chewblekka
Can hi and lo taps done. Carefully peeled, joined, soldered and heatshrunk.

Do you know if any of the wires going into J217 are postive switched.
Nearly impossible to get the connector off without removing the module and dont want to puncture any wires trying to look for one.

Would it be sw/bl or rt/gn? I see both are positive as per the wiring diagram but cant tell which one is switched and right one to tap into

All the switched 12v going to J217 are 5A, so you don't want to tap into those. I would just run the positive wire up the right fuse box, it's close enough anyways.

Thanks. Decided to pick it up from centre console, only need 10a connection.
Wasnt up for routing a wire under floor, carpet etc to the fuse box.
All pretty neat and got it working, surprisingly didnt need programming.
I like the deep throaty exhaust note!!

Will upload an audio file

Sounds great! Can you post up some pics of the install? I want to see how it looks underneath, etc.

Heres some...perhaps will post a diy thread, all clean and factory look including how its wired.
Wait till you hear the idle, love how it rumbles like an 80s v8 supercar
Best thing about this is when you want to go stealth then press a button or on the mobile app

Module doesnt need coding interestingly- i thought it will come up in the installation list, maybe its one of the no name ones.
Will have to see how its setup in the sq7
