parking light flash relay

I recently purchased my wife a Python 4104 Remote start keyless entry setup. when I started to do the install it had 2 wires I did not quite understand. connector h1/4 light flash isolation wire connect to pin 87a of light flash relay and pin h1/5 connect to pin 30 of relay my question is since both of these are on the load side what controls the trigger side . I am using xpresskit xk09 for vehicle interface And I am lost any help would be appreciated

Is there an internal "Jumper/Fuse" in the Python?  Most Viper units have it and that is how you set the

polarity of the H1/5 ( H1/11? ) Parking Light Output wire.  You can set it to either position and choose the appropriate vehicle wire to use.  Since no isolation is required with your Alero, H1/4 ( 87a) is not used.
