I was wondering if there was a better line to tap into to run the acc wire to the stereo other than fuse 22. This acc line shuts out immediately when the ignition is turned off. Is there a line that has the delay until the door is opened?

That is the million dollar question.
I have been looking for ever for this. and it appears most everyone here has been too.

some thought about messing with the relay or something from the power windows, but I never heard any more on that.

ok i think i've figured it out roughly... sorry for the delay... but i think i have a solution... though try the power window thing first. put a multimeter on the lead and see if you get power and if it shuts out when you open the door. if that is the case then a simple relay would work. if not i think i could design a circuit with a 555 timer that will keep power to your stereo until you open the door. basically i would make the timer and set it to about 10 mins have it wired to count down when the fuse 22 wire cuts power. and then have the main power to the circuit come from a relay that is triggered by the door plunger thing.

i will check later to see if there are any prebuilt timers that i we could use

maybe something like this would be even simpler:

I believe it's like a timer and relay in one.

you would connect a relay before this that is on the timers 12v+ post. It would be tripped by the door being opened which would cut power to the timer and shut everything down.

i think the 602 is the way to go

this is another alternative too

I dont see why would couldnt wind a RAP circuity in the fusebox most likely for the windows and do a relay on it, maybe if dad isnt home tomorrow I will tear into the vette and figure it out for you

don't you lose the rap feature when you remove the stereo though?

You only need to use Fuse #22 if you have a 2004 C5. All other year C5s have an accessory harness available in the passenger footwell. It supplies constant power, switched power, and ground. And the switched power works in the ACC position, not just the RUN position like Fuse 22.

You will lose RAP.

On the C6, PAC makes an adapter to allow you to keep RAP and not mess around with the switched power lead.

scott_fx

that is exactly what I am trying to do here. I'm trying to figure out a way to simulate RAP for those who want it. (I have mine hooked up to the Accessory harness in the footwell and I don't need rap since my computer has an automatic RAP feature anyways ) I'm just trying to figure out a way for everyone else to have RAP too

The PAC TR7 adapter has a time delay switched power feature. Not exactly RAP, but it would work to keep the stereo system on, even after the key is removed from the ignition.

TopDownTech

Top Down Tech just released the Accessory Valet. It decodes the body control module's RAP commands over the OBDII bus and provides a signal that can control aftermarket stereos. It will allow the aftermarket stereo to operate exactly as the stock unit did. Also, power is muted when the ignition switch is in the "crank" position, just like for the stock stereo.

In addition to the RAP output, there is a second output that tracks the headlamp controls. If connected to the dimmer/illumination lead, the head unit will dim its display for night driving.

The module needs an always hot +12V, ground, OBDII data, and then provides the two signals mentioned above.

As an convenient bonus, Window Valet users will find that the Accessory Valet also tracks the enhanced RAP modes.

We hope this product is a useful addition to your aftermarket audio systems.
