12v switched

[IowaTom]

Guys - I'd like to install a dash cam that only operates when my truck's running.  From this handy scan below, can I use any of the 296 or 297 lugs on my ignition switch to get what I'm after?  Thanks!

It looks to me that if you want power only in run you need to use 16 (ignition)

37 (power) + 296, 297 are connected in Accy, Off, Run and Lock.

The only one exclusive to power (37) in the  'Run' position is going to be #16

Thank you, Jim!  #16 it is!

Scott, your link takes me to a thread about judging the 2023 show...  

Tom, Id seriously consider using an add-a-circuit, but I have an '87 truck and my fuse panel is different.
Much cleaner and easier than messing with wires at the switch.

Fuse #9 controls the blower motor in your '85 and is only powered in run.



Edit:
Fuse 15 & 18 also seem to be powered only in run.
These are fuel selector and seatbelt warning/fuel pump control.

Whoops! Thanks Jim - fixed it

Thanks Scott!
That's a very well written tutorial.  

The extra input to 5&9 looks ideal for Tom. (and good for me to learn more about the 80-86 fuse panel)

Wow!! Super helpful stuff - as always!
Thanks so much, Guys!
