Need power source in fuse block tied to ignition

[rmart]

I'm adding some LED lights behind my grille (2014 GMC Sierra 1500 SLT) and need a power tap that's on only when the ignition is on.

 

I'm going to run out and get a power tester because I burned mine out but I figured I'd ask you genii if you knew which one might be usable.

 

In the fuse block under the hood I understand the #39 and the #53 slots are spares and in the fuse block on the driver's side of the dash I understand #'s 9, 19, 20, 24, 27, 28, 33, 36, 37, 45 are spares.

 

Anyone already have experience with what I need?

 

Thanks

You want this on every time the truck is running? Or is the ignition going to a switch or controller? I ask because there is a under hood source and a under dash source. Also people have controlled lights with the wireless control.

I'm looking for a power source for the switch so the lights will only come on when the truck is running. There will be a wired switch on the dash to control them.

 

Power to relay, ignition power to switch, switch to relay, relay to lights.

Oh and I wired a relay off all those post. So it was easier to install. Then I ran all my gauges and switches of it.
