Outer Limits 4x4 Board

hello guys just wondering if anyone here has the power windows on a delay relay.

as i want to use my power windows after my key has been turned off so i can close them then the power gets cut off after 30sec, like commodores have. whats the best way to do this.
any help would be great
cheers

You could use something like a turbo timer to do it.

Just wire it to keep power to the window circuit instead of wiring it to keep the engine running.

ive used this circuit to keep a few different things powered up in different vehicles works great but its several minutes rather than seconds but changing the components could cut it down

what vehicle is it you want to do this to?
