i bought the same model TT, shipped from Thailand delivered to Aust $60
it's not plug and play - from memory 3 or 4 wires need to be tapped into on the back of your ignition switch.
you will also need to run a wire form the handbrake switch to the TT - brown wire from memory. it's illegal to connect the handbrake wire from the TT to ground, it's a very unsafe practice.
i also found their colour code didn't match to the drawing! But being i sparkie i accepted the challenge!
i'd have the wiring connection at home for connection details of the TT to ignition switch.
yes, you'll have the issue or waiting for the TT to count down before you lock up.
if you need it, let me kow.
If you could forward a copy of that onto this thread for us it would be a great tool for other users and very handy for the member who just bought my one as the directions are very hard to read on the paper its all blurry but still can be made out.
Thanks,
Nath.
