Anyone know how to determine what type of factory door lock circuit the 2009 Yaris have?

If you mean positive or negative pulse, it is negative.

Thanks alot CTScott!! The alarm manual gave 8 different types and I narrowed it down to either:
-Three wire (+) 12 volt pulse controlling factory lock relays or
-Three wire (-) ground pulse contrlling factory lock relays.

Will post more further updates after installing the alarm. Thanks again CTScott!
