Are you sure the d/l circuit is 5 wire? Try this configuration, put outputs to negative for d/l relays, 85 to negative input on both relays, 87 and 86 to 10a fused 12v constant, 87a to switch side and 30 to factory side.

Best way to know if 5 wire or not is to cut one of the d/l wires and if they stop working then its 5 wire.

If the car has factory keyless entry, then the doorlock system isn't 5 wire polarity reversal. The car then uses a positive pulse system. Light blue for lock and white for unlock. Also check to see if you are using the correct light blue and white wires in the car. If it is a 5 wire system they will show 12 volts + when using the passenger side lock/unlock switch.
