Need help adding illuminated entry

First off, if you pulse the white wire at your courtesy light with ground, your lights should come on. and if your door locks were negative all you would need to do was connect a wire between the two with a diode (band facing the unlock wire). But since your door locks are positive all you need to do it change the polarity with a relay like this: 85 to unlock wire, 86 to 12v+, 30 to white coutesy light wire, and 87 to ground. You will also have to pulse that wire with your lock wire to turn the lights off i believe, which would require another relay. That is if pulsing the wire once turns on the lighta and pulsing it again turns them off. I am trying to remember how I wired my car to do this, it has been a while and i have negative door locks so i didn't need any relays, just diodes. Let me know how it goes or if you have any questions. Probe that white wire with a test light connected to ground and note how it works.J Rilla
