Wiring diagram 2006 Jetta

Going crazy looking for an accessory wire that is 12volts with key on/off when cranking. If anyone can help out it would be much appreciated.

There are a few places you can look. If you can get to the ignition harness you can use the run/acc wire which will be hot on startup. Usually any fuel/ignition relays will be hot when the car is starting and running. I usually just get the color codes for the ignition harness (the one coming from the steering wheel) and use the ACC/RUN wire when installing alarms or stereos.
