you have to tap into the black/orange wire in order for the alarm to think that the car is off. u're simply tricking the alarm into thinking that the car is off when u take out the key. then the TT can do its job.
as for the settings....u have 3 modes to choose from:
1 - Manual mode - u preset the amount of time u want the car to run.
2 - Auto mode LOW - 3 settings - #1, #2, #3.
3 - Auto mode HIGH - 3 settings - #1, #2, #3.
it's in the manual, i think page 2.
basically these are all the different ways to calculate time.
mode LOW measures RPM and how long u've been in each K of RPM.
mode HIGH measure how long the car has been on + how long u've been in each K of RPM.
bleh.......dont know if that makes sense.
what is also cool is that if for example u just want to roll down your windows and u're in Manual mode, the TT will still count down wahtever time u preset.
BUT if you're in Auto mode, the TT will not count down and the ignition will turn off as soon as you turn the key.
LOW mode will give u less time........if you are driving on a highway for 30 min, then u exit and drive 10 min on the smaller streets without boosting much, by the time u reach home and turn off your car the TT will be almost at 0.
HIGH mode with the same scenario will give u anywhere between 30 seconds to 1:20 depending which setting you're in.
