Hi all, '08 Tahoe: Is there a fuse I can tap off of (add-a-fuse) for switched power (only hot when iginition's on) in the fuse panel at the end of the dashboard on the driver's side? I tried a few and they all were hot all the time. Anyone know which number is only hot with ignition on? THx in advance!

 

i couldnt find one when i was hardwiring my radar detector so i ran a wire to a hot one and used a switch.

 

I did find this thread that looks promising. I haven't investigated it yet, but I have a feeling I'll find some switched 12v power somewhere in there.

 

Welcome to the forum,
try checking at the relay panel located near the upper left of the brake peddle...
pull the plastic housing off and probe some of the open ports...
I found hot all the time there(for my Garmin) but I believe there are some key on points also, this is on an 07 Tahoe

 

Thanks for this! In my '08 Tahoe, iIn the third bank/section/connector down on the left hand side, the first pin in the upper left is switched. It's connected to a pink wire. One next to it is red and white, thicker gauge, and always hot. I tapped into the pink one and it works great!!

 

Your welcome and thanks for taking the time to follow up with your findings
