1997 Volvo 850 Parklights

Yeah see the parklights are weird.  ANyways I have them hooked up as regular positive and they work fine...  I am putting in the valet 561r unit in by the way.  I got the switch inside the car working it seems to get messed up randomly if i keep trying to unlock form the valet unit's keypad.  I dont know if it has something to do with a factory security system or what.  I am making some progress, I have ignition controlled door locks working it locks and unlocks, but if i just want to use the keypad it will not work.  The funny thing is I can lock and unlock with the remote if the drivers door is open, the second I close the door, only lock works.  If I keep trying to unlock eventually the switch in the car will stop working.  So im thinking this car needs something to turn off factory security.

Well...the parking light are not 5 wire. Standard POS(+) pulse will work just fine!
