timed delay relay negative pulse

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.

thank you so much!
