I want to use this relay diagram (momentary to constant) to activate my domelight when I unlock my car. How do I wire it to switch off the domelight when my ignition key is turned? I can feed the relay a negative pulse from my OEM central locking relay, BTW I have neg doorpins

run a relay off the starter wire , fuse protect and diode isolate it to prevent issues. Run ground to the common and ground out to your relays out of normally closed. When the Starter power hits the relay and activates (opens) it the dome will terminate. The relay will then shutdown after cranking.

NOTE: if you run the relay off of IGN power it would also work but the relay would remain active until the key was shut off and although it would probably be okay, it could potentially cause issues with the relay by being on all the time. If you do it that way take into consideration the quality of the relay, the load capacity, and the fact its not a good idea imo.
