hi, so i have a pulsar 2005 model, i managed to turn on the lights wen i unlock the car.
Basically i found a wire on the driver door that is negative ONLY wen i unlock the car, and i hooked this up directly to a foglight wire i found (negative also). So now wen i unlock the car on the remote, it turns on foglights, nd wen i lock it turns them off.
Now i want to know how to use the DEI-528T timed relay to keep the foglights on for 20 seconds after i lock the car. thanks

You will need a second relay as an ignition inhibitor, wire as follows.
Relay 85 ground
86 to ignition
30 to ground
87a to black of 528t
87 not used
BLACK/ white to door lock neg pulse
Red to constant 12v+
Yellow to ground
Brown to to the neg fog light wire
Orange not used.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
