is there any way to automatically unlock the doors in my 07 f150 when i put it in park say?

 

guess not?

 

There's been a couple people who want it done on the Expys.

Maybe just make something like this?

Maybe tap into, say, fuse 27 for the ignition. Granted, this would unlock once you shut off the car.

I wonder if the brake shift interlock could be used to determine when the truck is in Park, without having to shut off the truck?

Might actually try to build this this weekend if I have nothing else to do.

EDIT:

At least on the Expys, the connector C505 (driver side lock switch connector), the pink/light green wire that come position 6 is the unlock signal. Not sure if it's a positive or negative.

The diagram from the above site has a negative output. If the unlock is positive, will need to do this:
