Hi everyone! I have a 2021 CX-5 Signature, and I plan to add external puddle lights (walk-up lights under the car). My goal is to wire them to the dome lights so they turn on when I unlock the car and turn off when I lock it. To avoid any issues with the dome light circuit's power limitations, I plan to use a relay and fuse wired to the dome lights.
However, I'm having trouble locating the 12V positive (+) and negative (-) wires for the dome lights under the dash. Does anyone know exactly where these wires are or have a wiring diagram to share?
Also, if I wire the puddle lights to the dome lights, would they stay on whenever the car is unlocked, even if the doors are closed? Would they also stay on when the dome lights are activated (e.g., when a door is opened)?
Alternatively, is there a better way to wire them to function like standard puddle lights? Ideally, I want them to activate only when the car is unlocked and turn off when it is locked, but not stay on unnecessarily. Would tapping into the car’s locking/unlocking signal or another circuit be a better option?
If anyone has experience doing something similar or suggestions for achieving this setup, I’d really appreciate your advice. Thanks in advance!
