Where is a good spot I can pull power from something on the always on BATT lead?

I'm hooking up a Sirius satellite tuner, and it needs power at all times, and the deck tells it to turn on/off.

Anyhow, on my older cars, there were usually leads I could plug straight into in the fusebox labeled BATT, IGN, or ACC. Pulling the cover off the fusebox inside the vehicle doesn't show anything like that on my '03 F150.

Any hints on where to look?

(I need to get a factory service manual for this sucker, I hate tearing into something that I'm unfamiliar with)

 

Why not run a fused lead to the battery or to the power distibution box just to the right of the battery on the firewall.

 

For lack of options I just ended up running to the battery itself.

I'm not familiar with the distribution block you speak of either.

But its all working now, took me all day to do everything though. Figuring out what panels come off and what panels weren't worth taking out was a real chore. I lost one plastic retainer on the molding in the rear (2.5 door cab) where the rear side seatbelts retract into. Its still stable enough without it, so I just slapped everything back together.

Sounds pretty danged good!

 

any open slot in the fuse box would be good just use a test light with the key off and look for a terminal with power

 

I ran a test light to all the open/blank fuse terminals in the fusebox. None of them lit my test light.
