So I want to wire my cold cathodes to my parking lights as well so that when my car unlocks or locks the cold cathodes flash with the parking lights. Now I know I could wire another switch to include the power to my lights to the switch and from the switch to the cathodes but then when I have my lights on for driving that would activate the cathodes as well. So I need to know how to wire my cathodes to flash when I lock and unlock my car I guess
Thanks!

you basically make two positive leads. one going to a switch that goes to an always on powers, the other leading either to the parking lights, or the alarm

but if I wire it to my parking lights then i would constantly have to change the switch back and forth so that when I am driving the cathodes are not on and if I then wanted the cathodes to flash when I park and lock the car i would have to change the switcha again

true. umm. hook it to the alarm side of the relay that goes to the turn signals

depending on what exactly you want,

can be as simple as a couple of 25 cent diodes placed in the alarm and
cathode leads
or
a nice little relay setup would allow 2 positives- one from your switch for
manual control and other from your alarm for flashing.
each would control independently of the other.
