Fuse question
As soon as the weather breaks (it friggin snowed today in MD), I plan on adding a dash cam and fuzz buster to my ’04 vert. But I want the power to be controlled by the ignition switch. So I bought an Add on Circuit adapter to plug into an existing fuse. But I am not sure what fuse in the passenger fuse box is the best one to tap. I would appreciate any advice from those that have done this. Thank you.

There are two spare circuits located in the passenger footwell - one switched and one unswithced. There are numerous threads that discuss how to use these spares that were supplied with the car.

Thanks for your replies. In one of the threads I looked at it suggested to use the add on fuse (called a piggy fuse) and insert into one of the existing fuse slots that use the switch. Is this a good idea or not? Sorry, electical drawings are not my expertise. Yep, The Owners manual shows two blanks. I should have looked in the manual first. Sorry. I guess I can test each one to see if is hot with or without the inition on.
Thanks for the replies.

Lol... I have gotten too paranoid about electrical problems I'm scared to replace a bulb that's out....cause I'll screw something up and then when I step on the brake the headlights will pop up....

OK, if that one's not good enough, try this one.
Here's my final try. Pay SPECIAL attention to post number 7, and several of those that follow.

Tip: forget the fuse tap bs and do it the right way.

Did you look at the link I posted previously?

I wonder why they stopped the pony tail wires? To easy? Made too much sense?

There's no reason to use a fuse tap as the provided wires mentioned are easy to get to and to use. Also, the installed fuses that protect the various circuits may not have the extra amperage capacity to handle additional electrical loads.

I would suggest using the ignition switched lead that is in the passenger side foot well. The C5 Owner's Manual tells you how to access the harness and how to connect a device to the wire. There is also a ground wire there so you don't hae to search for a ground point. The two wires (one ignition switched and the other always hot) can handle up to a 15A load.

Fuse 11 (20 amp) is the ignition ON feed for Accessory Power in the T/P fuse box. You can see it listed in your owners manual and in the fuse box diagram.
It does NOT provide power to anything else. In the 2004 FSM it actually shows a Yellow wire feeding from the fuse box and shows it as cut and taped. The Yellow wire may or may not be there. I recommended if it is there to use it if he wanted to. If not to install a fuse buddy/adapter in that fuse location for the power feed. There is nothing wrong with using these devices so long as you know what you are doing and don't overload circuits. In this case you can add up to 20 amps.
I suggested for his application he use a 5 amp fuse since his load will be less than that and I doubted the radar detector and camera wiring could handle 20 amps waiting for the fuse to blow.
The fuse box is open at the bottom and would be way to feed the power out.
I recommended he use Ground G202 which is at the base of the A-pillar on the passenger side. You have to remove the plastic cover to expose the ground.
Let me know if you have any questions. As always I can always provide circuit schematics from the FSM if desired.

I would use Fuse 1. You could use Fuse 7 or Fuse 1 for an ALWAYS HOT source.
Fuse 7 is shared with the cigarette lighter by the HVAC unit and Fuse 1 is shared with the Console Auxiliary Power source between the 2 seats. Based on what you want to hook up would dictate the use of either port.
GM provides both of these fuses for auxiliary power wires in the 97-03. However, the 2004 schematic is no different in their use and can be used in the same manner.
If using Fuse 7, I would NEVER use the cigarette lighter to be on the safe side since that is a high current draw when in use. If you are using that port for an iPod or equivalent I would not be concerned.
If I need to work with you on what you want to do let me know. Hope this helps.
