parking lights not flashing python 991

I just installed a Python 991 to replace the Python 871xp I had in my 2008 Honda Civic Si. Everything is working with the exception of the parking lights. I tapped into the same wires used for the previous alarm. The 871xp had one white wire that was used to tap into the parking light wire. The 991 has 2 wires - the white wire is for the parking light output and the WHITE/ brown wire is for the parking light isolation wire (pin 87a of onboard relay). I tapped the white wire straight into the (+) Parking Light Wire at the fuse box but I have no idea what the WHITE/ brown wire is for. Could anyone please help me resolve this problem?

Thanks,
