how can you do this so they turn on when your parking lights are on? also, is it possible to wire them up so when you hit your lock button they flash with the rest of the lights?

 

you'd just need to find the wiring that would have gone to your fog lights (dont know if you have fogs or now getting some) and they wire up the power to go to the new fogs + ground them, and the same power that goes to the oem fogs would go to your aftermarket fogs.

or to get them to flash with the corners, you'd need to wire them up to those, that way when they flash so will your fogs.

 

but if i wire them to my side markers, will they flash like crazy?

 

you've got to bump it up
