4x10 on a Manual GTI
Finally, after 2 years, I have gotten my 4x10 remote start to work on my 2011 GTI. For those wanting to add remote start to their GTIs, I have attached a wiring diagram that I created showing the proper wire connections.
This is basically a "Type 3 with Regular Key"" installation retaining the "Ready Mode" for manual transmission, with everything not required taken off the diagram, and I added wire colors to connections Directed didn't include.
One big change is that it was easier to connect the FT CAN wires at the "C plug" instead of a the "Steering Column Control Unit". They are the twisted wires (of the same color as on the 4x10 wires you are trying to connect) and they are right next to the clutch wire (in the bundle of wiring). I wanted to reduce the number of wires connected at the "Steering Column Control Unit", as space under the steering column is already tight, and I mounted my Valet key under there to limit the number of wires coming out from under the steering wheel to only 4.
I also installed a Viper 7656V for the added range, I will keep one of the remotes at my house and one at my work so I can start my car without having to get within 35 feet of the car (using the OEM remote). This was very easy, just plug the green 6 pin connector to its required port, run the harness up along the A-pillar, and connect the other end of the harness to the antenna module and attach to your windshield with the double sided tape.
Then it's time to find a place to hide the 4x10, I hid mine behind the footwell trim (the one with the hood release), it fit nicely behind it without having to remove the trim, add a little packing foam so it doesn't rattle behind the trim.
Other than that, follow Zrickety's procedure and you are all set.
Zrickety modified his wiring to work like an automatic, and remove the "Ready Mode" sequence. I have included a wiring diagram for that modification. It is basically cutting the yellow loop (Auto/Manual Transmission), and then connecting the Dark Green wire to the Purple/White instead of the Dark Blue. You then need to change the output of the Dark Green wire to "Grounded when Locked" when flashing the 4x10 unit with the XpressKit. This change is on the last page with all of the AUX options, at the very bottom.
WARNING: Installing the 4x10 set up in this way (Auto Mode), the car will start when you hit the OEM lock 3X or with an auxiliary remote start button, REGARDLESS of it being in neutral or in gear! Install at your own risk. There is a bit of safety, due to it only outputting a signal to the clutch wire if the doors are locked, so if the doors are unlocked, the car will keep asking for you to depress the clutch pedal instead of starting. Most people don't work under the hood or under the car when the doors are locked, so you shouldn't kill yourself if you hit the remote start button on accident while working on your car. BUT, if you hit the remote start button while your car is parked and in gear, it will leap forward and crash into whatever is in front of it.
