i've seen some post about tt's and the factory alarm. i just installed mine today and wanted my tt to work with my factory alarm.
here ya go
Originally posted by SpicyTuna You can use the stock alarm with a turbo timer. If you just plug in the harness it will leave you without your stock alarm. To get this working, that is where the hacking begins. Take an inline fuse holder, and crimp spade connectors onto each end. The spades should be the same size as the blade of a fuse. Pull the cover off of the driver's side fuse box - it is just to the left of the clutch pedal. Pull the fuse marked "gauges" (the fuse box cover is labeled in case you dont know which fuse that is) and put one end of the inline fuse into the lower slot. The other end of the inline fuse goes into the lower slot of the bottom left-hand corner fuse hole.
It is much less complicated than it sounds.
