what do you mean?

you want it to idle faster?

if so just screw in the idle screw a tad...but remember how far you'll need to move it back when testing sensors if need be

I had an old buick that had an idle kick up solenoid that would raise the rpms about 200 when the a/c clutch was energized. You could engineer something like that, but how many watts are you using when you run the electronics?

Are you experiencing a voltage drop at idle on the 12 volts side (about 14.5 when engine is running) when you run your equipment? If so, I'd be inclined to think you may need a larger output alternator to be able to handle the load you are using.

yes the amp gauge goes down, when im running all this stuff and i just picked up a new alternator this fall, and it seems to put out good, and when i just barely give it some gas to get the rpms up its fine, but not sure how much it pulls it down i just know the amp goes down!

I don't think I've ever seen one available to do this in the aftermarket. If you want a simple way to do this, buy a manual choke cable and use that to idle it up. I know exactly what you're talking about and what you want to do. I've seen it done with the toggle switch on the old 6.9 and 7.3 IDI.

theres a adjustment on the throttle body, wouldnt mess with it but you could find out what thickness feeler gauge placed between the screw and its stop makes it idle where you want it to idle, then just mount it on a string near it or somewhere in your cab, and slide it in there when you want a higher idle. im sure you could get creative with a setup, electric or manual, to make it work also.

yea i figured there was a wire you could tap into somwhere, but the cable was my next option, maybe someone can come up with something befor i make a decision.
